Isaiah 28:27

Clarke's Commentary

Verse Isaiah 28:27-28. Four methods of threshing are here mentioned, by different instruments; the flail, the drag, the wain, and the treading of the cattle. The staff or flail was used for the infirmiora semina, says Jerome, the grain that was too tender to be treated in the other methods. The drag consisted of a sort of strong planks, made rough at the bottom, with hard stones or iron; it was drawn by horses or oxen over the corn sheaves spread on the floor, the driver sitting upon it. Kempfer has given a print representing the manner of using this instrument, Amaen. Exot. p. 682, fig. 3. The wain was much like the former; but had wheels with iron teeth, or edges like a saw: Ferrata carpenta rotis per medium in serrarum modum se volventibus. Hieron. in loc. From this it would seem that the axle was armed with iron teeth or serrated wheels throughout. See a description and print of such a machine used at present in Egypt for the same purpose in Niebuhr's Voyage en Arabie, Tab. xvii. p. 123; it moves upon three rollers armed with iron teeth or wheels to cut the straw. In Syria they make use of the drag, constructed in the very same manner as above described; Niebuhr, Description de l'Arabie, p. 140. This not only forced out the grain, but cut the straw in pieces for fodder for the cattle; for in the eastern countries they have no hay. See Harmer's Observ. I. p. 425. The last method is well known from the law of Moses, which "forbids the ox to be muzzled, when he treadeth out the corn;" Deuteronomy 25:4.

Bridgeway Bible Commentary

28:1-33:24 HEZEKIAH AND THE ASSYRIANS

Before reading Chapters 28-33, readers should be familiar with the historical background found in the introduction under the heading ‘Judah’s new policies under Hezekiah’. Hezekiah reversed the policies of his father Ahaz. Whereas Ahaz sought help from Assyria to oppose Israel and Syria, Hezekiah sought help from Egypt to oppose Assyria. Isaiah opposed both policies alike. Faith in God, not reliance on foreign powers, is Judah’s only hope for survival. The messages collected in these chapters were probably delivered by Isaiah during the three or four years from Hezekiah’s revolt against Assyria to the miraculous rescue of Jerusalem in 701 BC.

Bad leadership and its results (28:1-29)

Although his rebukes are directed mainly against Judah, Isaiah opens the section with a short message he once preached against Israel. (The reason for this, as Isaiah will soon point out, is that the message is now equally relevant to Judah.)
The nation’s rulers are a lot of drunkards, who live only to enjoy themselves and do not care about the welfare of the people. Because they are heavy wine-drinkers, they are likened to a flourishing vineyard. A severe hailstorm (symbol of the Assyrian invasion) will now destroy the vineyard, and enemy soldiers will trample the grapes underfoot (28:1-4). Nevertheless, the few who remain faithful to God will not be forsaken. God will give them his wisdom and strength, enabling them to come through the crisis successfully (5-6).
At this point Isaiah makes it plain that his prophecy against Israel applies also to Judah. Its leaders also are drunkards, even the religious leaders (7-8). They are annoyed at Isaiah for his persistent teaching, and indignantly ask him if he thinks he is teaching children. They are tired of hearing his same simple message over and over, telling them to turn from their evil ways and trust in God (9-10). Through Isaiah God has promised them true peace and perfect rest. If they refuse to listen to these clear and simple words, God will speak to them in a different language, one that they will not understand. That is, they will hear the foreign language of the Assyrian armies whom God sends against them to punish them (11-13).
Judah has made an agreement with Egypt to rebel against Assyria, but God sees it as a rebellion against him. It is like an agreement with the world of the dead instead of with the living God. It is based on falsehood instead of on God’s truth (14-15). God is the only reliable foundation on whom Judah can build its hopes. If the Judeans trusted in him, they would not need to go running to Egypt for help (16). God will act in righteous judgment against his faithless people. Their alliance with Egypt will be as powerless against Assyria as a temporary shelter is against raging floodwaters (17-18).

Day and night the ferocious Assyrian attack will go on. The people of Judah will find that all their preparation has not been enough to give them the comfort they hoped for (19-20). In the place where David punished his enemies, David’s people will be punished by their enemies. And the more they ignore Isaiah’s warnings, the more difficult it will be for them to escape the punishment (21-22; cf. 1 Chronicles 14:11,1 Chronicles 14:16).

A farmer knows from experience that he must use different methods of planting and threshing for different crops. God likewise uses different methods in his dealings with people, and his actions are always based on his perfect knowledge (23-29).

Coffman's Commentaries on the Bible

“Give ye ear, and hear my voice; hearken, and hear my speech. Doth he that ploweth to sow plow continually? doth he continually open and harrow his ground? When he hath leveled the face thereof, doth he not cast abroad the fitches, and scatter the cummin, and put in the wheat in rows, and the barley in the appointed place, and the spelt in the border thereof?. For his God doth instruct him aright, and doth teach him. For the fitches are not threshed with a sharp threshing instrument, neither is a cart wheel turned about upon the cummin; but the fitches are beaten out with a staff, and the cummin with a rod. Bread grain is ground; for he will not be always threshing it; for though the wheel of his cart and his horses scatter it, he doth not grind it. This also cometh forth from Jehovah of hosts, who is wonderful in counsel, and excellent in wisdom.”

This is a beautiful little parable drawn from the agricultural industry, the point being that such things as plowing and threshing have their specific purposes; therefore God’s punishments of people, whether his own, or his enemies is purposeful, always looking forward to the projected results.

Fitches were a common herb, cultivated as a forage plant, or `black cummin,’ whose aromatic seeds were a favorite condiment of the Greeks and Romans.”The New Bible Dictionary, p. 425. “Spelt was what we would call rye, or an inferior kind of wheat.”Ibid., p. 1209. Even the farmer who belonged to a class of people probably despised by the drunken leaders of the people, knew that all of God’s law must be respected and obeyed if one is to reap a harvest from the earth; yet those foolish leaders fancied that they could wantonly forsake all honor and morality, live in shame and debauchery, and that somehow, in spite of all that, God would enable them to go on unhindered in their licentious ways. What a terrible awakening awaited them!

Barnes' Notes on the Whole Bible

For the fitches are not threshed with a threshing instrument - The word used here (חרוּץ chârûts) denotes properly that which is pointed or sharp, and is joined with מורג môrag in Isaiah 41:15 - meaning there the threshing dray or sledge; a plank with iron or sharp stones that was drawn by oxen over the grain (compare 2 Samuel 24:22; 1 Chronicles 21:23). In the passage before us, several methods of threshing are mentioned as adapted to different kinds of grain, all of which are at the present time common in the East. Those which are mentioned under the name of the ‘threshing instrument,’ and ‘a cart wheel,’ refer to instruments which are still in use in the East. Niebuhr, in his “Travels in Arabia,” says, (p. 299,) ‘In threshing their grain, the Arabians lay the sheaves down in a certain order, and then lead over them two oxen dragging a large stone.’ ‘They use oxen, as the ancients did, to beat out their grain, by trampling on the sheaves, and dragging after them a clumsy machine.

This machine is not a stone cylinder; nor a plank with sharp stones, as in Syria; but a sort of sledge consisting of three rollers, fitted with irons, which turn upon axles. A farmer chooses out a level spot in his fields, and has his grain carried thither in sheaves, upon donkeys or dromedaries. Two oxen are then yoked in a sledge; a driver then gets upon it, and drives them backward and forward upon the sheaves; and fresh oxen succeed in the yoke from time to time. By this operation the chaff is very much cut down; it is then winnowed, and the grain thus separated.’ ‘This machine,’ Niebuhr adds, ‘is called Nauridj. It bas three rollers which turn on three axles; and each of them is furnished with some irons which are round and flat. Two oxen were made to draw over the grain again and again the sledge above mentioned, and this was done with the greatest convenience to the driver; for he was seated in a chair fixed on a sledge.’ See the illustration in the book to get an idea of this mode of threshing, and of the instruments that were employed.

Neither is a cart wheel - This instrument of threshing is described by Boehart (Hieraz. i. 2. 32. 311), as consisting of a cart or wagon fitted with wheels adapted to crush or thresh the grain. This, he says, was used by the Carthagenians who came from the vicinity of Canaan. It appears to have been made with serrated wheels, perhaps almost in the form of circular saws, by which the straw was cut fine at the same time that the grain was separated from the chaff.

But the fitches are beaten out with a staff - With a stick, or flail. That is, pulse in general, beans, pease, dill, cummin, etc., are easily beaten out with a stick or flail. This mode of threshing is common everywhere. It was also practiced, as with us, in regard to barley and other grain, where there was a small quantity, or where there was need of special haste (see Ruth 2:17; Judges 6:11).

Smith's Bible Commentary

Chapter 28

Chapter 28. Now the prophet turns to the local present issues. He is now... he's gone off down the road to the end of things. Now he comes back and he begins to speak of the Northern Kingdom, the major tribe was Ephraim there in the Northern Kingdom. And so the nation of Israel is addressed as Ephraim, its major tribe.

Woe to the crown of pride, to the drunkards of Ephraim, whose glorious beauty is a fading flower, which are on the head of the fat valleys of them that are overcome with wine! Behold, the Lord hath a mighty and strong one, which as a tempest of hail and a destroying storm, as a flood of mighty waters overflowing, shall cast down to the earth with the hand. The crown of pride, the drunkards of Ephraim, shall be trodden under feet ( Isaiah 28:1-3 ):

So Isaiah is here predicting the invasion of the Northern Kingdom by Assyria. The Northern Kingdom was filled with pride. The Northern Kingdom was filled with prosperity. The fat valleys. The Northern Kingdom was filled with a careless attitude as people were seeking mirth and merriment and pleasure, rather than God, and judgment was hanging over their heads. And yet they were giving themselves just to drunkenness. Here they were standing in a critical place in their history. They're about to be devoured by their enemies. The nation is at the end of the road. They're not going to go any further. And yet the attitude of the people is not a serious attitude of repentance towards God and seeking God, but it is an attitude of just seeking pleasure and just drinking and trying not to think of the heavy judgment that was hanging over them.

It seems that people are always oblivious. That is, the general public is oblivious, though doom is hanging over it. And so it will be when Jesus comes. Jesus said, "As it was in the days of Noah, so shall it be at the coming of the Son of man" ( Luke 17:26 ). For the days of Noah, the people were just eating, drinking, the same thing of just going on and pretending like there's nothing wrong. Not realizing that the judgment of God is hanging over them and they're about to be destroyed. Right until the day that Noah went into the ark, the people were going on with just things as usual, drinking and partying and the whole thing. Until Noah was in the ark and it began to rain. And suddenly they woke up. But then it was too late.

Now here is Ephraim. Judgment is hanging over them but they're going on in drunkenness. In their pride and all. And not until Sennacherib comes down with the Assyrian forces, and then it's too late.

We look at the world today and we see people that are just so oblivious to the impending judgment of God that is hanging over the world today. We see all of these forces of evil. We see people so outspoken with their evil, so brazen in their display of evil. Things that people used to be ashamed of and would seek to deny or hide from, now they are parading in the streets with banners. Advertising their sin. And we are ripening towards judgment. And the heavy hand of God is hanging over us and God's judgment is about to fall. And yet people seem to be totally oblivious to it. Going on seeking pleasure. Going on in their pride. And seeking the prosperity not realizing that suddenly it's going to come and God's judgment is going to strike.

So the sad picture of Ephraim and the prophet speaks out against it. Ephraim's going to be trodden underfoot. And within three years from the time of this prophecy it happened. The great and glorious nation that God had favored and blessed was destroyed. And I really feel that the United States is in much the same position. A great and glorious nation which has been blessed of God, but I believe that the heavy cloud of God's wrath hangs over us because of the things that we have allowed and promoted in this land. And it speaks of

The glorious beauty, which is on the head of the fat valley, shall be a fading flower, and as the hasty fruit before the summer; which when he that looketh upon it seeth, while it is yet in his hand he eateth it up. In that day the LORD of hosts will be for a crown of glory, and for a diadem of beauty, unto the residue of his people ( Isaiah 28:4-5 ),

But here they were glorying in the crown of glory of the fat valleys and so forth, but they're going to be wiped out. Now even those that were being warned by the prophet just made fun of the prophet.

But they also have erred through wine, and through the strong drink they have gone out of the way; the priest and the prophet have erred through strong drink, they are swallowed up of wine, they are out of the way through strong drink; they err in their vision, they stumble in their judgment ( Isaiah 28:7 ).

And God speaks out against the drinking and how it has perverted their minds. Deadened and dulled their senses. And has turned them out of their way bringing them into error. Causing them to err in their vision and in their judgment. Drinking, it seems, always clouds a person's vision and actually destroys good judgment. Destroys your inhibitions. People do the dumbest things when they're drunk. Things that they would never do when they were sober. But it just always messes up your judgment.

You don't have good judgment when you're drinking. And we recognize that. Our laws recognize that. That's why we have laws that you're not to drive when you've been drinking because it messes up your vision. It messes up your judgment. And yet, here the people were they were giving themselves over to this. Messing up their lives. And God's heavy hand when you need to have clear insight, when you really need to see what's going on, you can't see because you're into the liquor. When you need to have good judgment and make the right moves, you don't have the ability to do so. The liquor has clouded your minds. The prophet speaks very graphically of them.

For all tables are full of vomit and filthiness, there isn't a clean place [around them] ( Isaiah 28:8 ).

But yet they mock at the prophet of God. They say to the prophet of God,

Whom shall he teach knowledge? and whom shall he make to understand doctrine? them that are weaned from the milk, and drawn from the breasts ( Isaiah 28:9 ).

In other words, who is he going to teach? He ought to go down and teach the little babies that have just been weaned from the breasts. Let him teach the preschoolers. Who is he going to teach? For his teaching

Precept is upon precept; line is upon line; here a little, there a little ( Isaiah 28:10 ):

But the prophet declares that God has declared:

For with stammering lips and another tongue will he speak to this people. To whom he said, This is the rest wherewith ye may cause the weary to rest; and this is the refreshing: yet they would not hear ( Isaiah 28:11-12 ).

Now interesting this verse is couched in here and you wonder what in the world is that verse about and what does it have to do with the context? As he's talking about Ephraim and the judgment that is coming and the blurred vision and the distorted judgment because of their drinking and all. And their mockery of his teaching methods saying you ought to be teaching kindergarteners for his teaching is so simple. Line upon line, precept upon precept. And then out of the middle of this, "For with stammering lips and another tongue will he speak to this people. To whom he said, 'This is the rest wherewith ye may cause the weary to rest; and this is the refreshing,' and yet they would not hear."

Now, Paul the apostle in writing to the Corinthian church about the abuse of the gift of tongues, as he speaks to them of this gift of tongues, he picks out this little verse and says this is what God was talking about when in Isaiah He said, "For with stammering lips and another tongue will I speak to this people. And this is the rest wherewith I will cause the weary to rest." Interesting. Paul picks that out and interprets that as a reference or a prophecy of the gift of speaking with other tongues that God would pour out upon the church. And that the gift of speaking in tongues would be a restful experience to those who exercised it. "This is the rest wherewith I will cause the weary to rest." And so it would be a very restful experience to those who would exercise the use of that gift. Very interesting, very fascinating.

And I have found that in my own devotional life, when I have a problem and I don't know how to pray over a particular situation, or I have a problem and I want to praise God and I feel a total inadequacy in English, that as I begin to praise the Lord in the Spirit or I begin to pray in the Spirit that it is such a restful experience. And I just find great rest in it. Great peace in it. And so Paul picks this out as a prophecy concerning those that would exercise that gift in their personal devotional life that it would be just a restful experience. And then he gets right back into the subject again.

But the word of the LORD was unto them precept upon precept, precept upon precept; line upon line, line upon line; here a little, and there a little; that they might go, and fall backward, and be broken, and snared, and taken ( Isaiah 28:13 ).

In other words, it was so simple that they would stumble over it. They wouldn't hear it. They wouldn't obey it. And thus, they would be snared and taken.

Wherefore hear the word of the LORD, ye scornful men, that rule the people ( Isaiah 28:14 )

And it not only is Samaria, but now,

in Jerusalem. Because you have said, We have made a covenant with death, and with hell are we at agreement; when the overflowing scourge shall pass through, it shall not come to us: for we have made lies our refuge, and under falsehood we have hid ourselves: Therefore thus saith the Lord GOD, Behold, I lay in Zion for a foundation a stone, a tried stone, a precious corner stone, a sure foundation: he that believeth shall not make haste. Judgment also will I lay to the line, and righteousness to the plummet: and the hail shall sweep away the refuge of lies, and the waters shall overflow the hiding place. And your covenant with death shall be disannulled, and your agreement with hell shall not stand; when the overflowing scourge shall pass through, then you shall be trodden down by it ( Isaiah 28:14-18 ).

You may say, "Well, we've made an agreement with hell or death and we're in agreement with hell. It's not going to touch us. You warn us, you say judgment; not going to hit us." And made refuge your lies. But God's going to sweep away your refuge and the judgment shall come and you'll be overthrown by it. But in the midst of it, the Lord has set for a foundation a stone, a tried stone, a precious cornerstone. That's a sure foundation. That's something that won't let you down. That's something you can rest in. The sure foundation that God has established. Jesus Christ, the precious cornerstone which was set at naught by the builders, but the Lord has made Him the chief cornerstone.

Now these people are mocking the prophet. They said, "Hey man, don't try to scare us with hell. We've got a covenant with hell. We got an agreement. We've made a covenant with death. And we're in agreement with hell. It doesn't bother us." The prophet says, "Your covenant is not going to stand. It's gonna be broken.

For [he said] your bed is shorter than what you can stretch yourself upon it: and your coverings are narrower than what you can wrap yourself in it ( Isaiah 28:20 ).

There are people who like to mock God and like to scoff at the warnings of God. There are people who seek to find rest in philosophy. There are people who seek to find rest in religion. There are people who are seeking rest in liquor, in pleasure. There are people who are seeking rest in prosperity. But of all of these things it must be said the bed is too short and the blankets are too narrow; you can't find real rest in these things. You'll never find satisfaction in prosperity. You'll never find peace in pleasure. There's only one place of real rest and peace and that is in the sure foundation that God has set. The precious cornerstone, Jesus Christ. The only place you'll ever really find rest is resting in Jesus. In His finished work for your salvation. You'll never find rest in religion.

Now here he speaks about the religious leaders getting drunk. And thus not seeing clearly, their judgment perverted. I think that drinking among the clergy is an abomination. Paul said to Timothy that if a man was to be an overseer in the church, that he was not to be given to wine. And I think that that applies to every minister of God. God said to Moses, "When Aaron and his sons come in before the altar, make sure that they haven't been drinking. For they must be clean who bear the vessels of the Lord."

There's an intimation that the two sons of Aaron that were killed by the fire of God that came out of the altar were killed because they were a little under the influence. When they saw the fire and got all excited, everybody was shouting and they grabbed the little incense burners and took the coals off the fire and began to offer strange fire to God, the fire of God came out from the altar and consumed them. Their judgment was twisted because of their drinking. And thus the warning came after that. And after the death of the two sons, the word of the Lord came to Moses saying, "Go unto Aaron and say unto him, 'Tell your sons and all that when they come in before the Lord that they're not to be drinking.'" God doesn't want any service out of false stimulation, false fire.

So today people are trying to find rest in religious experiences and it is a tragedy that there are churches that will tell you that you can rest in your infant baptism. "You don't have to worry about being saved. Were you baptized when you were a baby? That's all it takes. You were saved when you were baptized." The bed's too short. You can't rest in that. It takes more than having water sprinkled in your face and words mumbled over you when you were a child to save you. It takes an active, believing, trusting faith in Jesus Christ to bring salvation. He that believeth shall find the rest. He'll not be making haste or in frenzy.

Those who tell you that you had an emotional experience twenty-five years ago, you came forward in an altar call, and you wept, that that emotional experience is sufficient. You were saved. I don't care what happened to you twenty-five years ago; I want to know what is your present relationship with God. You can't be saved by past experiences. You are being saved by your present relationship with Him. Past experiences are just that-past experiences. Unless they have been transmitted into my present relationship.

Paul the apostle speaks of his experience on the Damascus Road saying, "Those things which were gain to me, I counted loss" ( Philippians 3:7 ). He was writing thirty years later to the Philippians. I counted them loss there on the Damascus Road. The whole past, man, is junk. And he said, "Yea, doubtless, I do count them thirty years later as I'm writing to you now, those old things which were once gain to me, which I counted loss on the road to Damascus, I still count them but refuse that I may know Him."

But you see, a lot of people twenty-five years ago counted the old life as loss when they came to the knowledge of Jesus Christ. But then in the meantime, they've gone right back. And they're living the old life. They're not serving the Lord. They're not walking with Jesus. They're not living in the Spirit. You ask them about their salvation, "Oh, I had the most glorious experience. I felt this glorious peace and this wonderful warmth that came all over me. And a tingling down my spine and I just sat there and wept before the Lord." What about now? "Oh well, you know, I haven't been to church for years and I really don't see any need of having Christ in my life because, after all, I had that glorious experience then." Oh no, you can't rest in some past experience. You need a vital, living relationship with Jesus today. Jesus said, "Abide in Me and let My words abide in you. For if any man abides not in Me, he is cut off, cast forth like a branch, and is withered; and men gather them together, and cast them into the fire" ( John 15:4 , John 15:6 ). "Abide in Me and let My words abide in you."

So he goes on.

For the LORD shall rise up as in mount Perazim ( Isaiah 28:21 ),

That's where David at mount Perazim smote the Philistines and called the place Perazim because God made a breach there against the Philistines.

he shall be wroth as in the valley of Gibeon ( Isaiah 28:21 ),

That's where Joshua said, "Sun, stand still" ( Joshua 10:12 ), in order that they might have enough time to wipe out their enemies.

that he may do his work, his strange work; and bring to pass his acts, and his strange acts. Now therefore be ye not mockers, lest your bands be made strong: for I have heard from the Lord GOD of hosts a consumption, even determined upon the whole earth. Give ye ear, and hear my voice; hearken, to my speech. Doth not the plowman plow all day to sow? ( Isaiah 28:21-24 )

In other words, hasn't God made all of this preparation and will He not go ahead and carry the thing through? And the whole idea is, yes, God will carry the whole thing through. "

Dr. Constable's Expository Notes

A call for repentance 28:23-29

How would the leaders of Judah respond? Would they continue in their chosen course of action and so suffer the fate of the Northern Kingdom, or would they repent and experience a milder judgment? Isaiah ended this "woe" by illustrating the alternatives and urging repentance (cf. chs. 5-6).

"Isaiah here proves himself a master of the mashal [proverb]. In the usual tone of a mashal song, he first of all claims the attention of his audience as a teacher of wisdom." [Note: Delitzsch, 2:14.]

Dr. Constable's Expository Notes

Likewise a farmer threshes dill, cummin, and grain in different ways. This is also wisdom that Yahweh of armies teaches. A simple farmer learns how to plow, plant, thresh, and grind from God, by studying nature, and as he applies what God teaches, there is blessing. How much more should the sophisticated leaders of Judah learn from Him to trust Him.

". . . God measures the instruments of His purpose to the condition of His people; He employs what will best carry out His holy will." [Note: Young, 2:301.]

"The farmer does not plow for the sake of plowing, but rather to prepare for his intended crop. So also God prepares his garden for the crop he wishes to reap-the crop of righteousness from a holy people. To this end God must employ the cutting and crumbling force of disciplinary judgments, perfectly adjusted to Israel’s spiritual needs, just as the farmer (using the intelligence God gave him) uses the proper threshing instruments for each type of grain." [Note: Archer, p. 629.]

An implication of these two parables (Isaiah 28:24-25; Isaiah 28:27-28), not stated, is that God might deal differently with the Southern Kingdom than He dealt with the Northern Kingdom. The Jerusalemites should not conclude that because God would allow the Assyrians to defeat the Ephraimites, the same fate would necessarily befall them. A change of attitude could mitigate their judgment. So this whole "woe" ends with an implied offer of grace.

As things worked out, of course, God did allow an invading army to take the Judahites into captivity, after a different invading army had first taken the Israelites captive. But that did not happen at the same time. Sennacherib destroyed Samaria but not Jerusalem. God postponed Judah’s judgment because He found a measure of repentance there.

Gill's Exposition of the Whole Bible

For the fitches are not threshed with a threshing instrument,.... A wooden sledge, dray, or cart, drawn on wheels; the bottom of which was stuck with iron teeth, and the top filled with stones, to press it down with the weight thereof, and was drawn by horses, or oxen, to and fro, over the sheaves of corn, laid in proper order, whereby the grain was separated from the husk: :- but fitches, the grain of them being more easily separated, such an instrument was not used in threshing them:

neither is a cart wheel turned about upon the cummin; the cart wheel of the above instrument was not turned upon the cummin, that being also more easily threshed, or beaten out, and therefore another method was used with these, as follows:

but the fitches are beaten out with a staff, and the cummin with a rod: in like manner as corn is with us threshed out with a flail; so the Lord proportions the chastisement, and corrections of his people to the grace and strength that he gives them; he afflicts them either more gently, or more severely, as they are able to bear it; with some he uses his staff and rod, and with others his threshing instrument and cart wheel; some being easier and others harder to be wrought upon by the afflictive dispensations of Providence; see 1 Corinthians 10:13 or this may point out the difference between the punishment of wicked men and the chastisement of the saints.

Henry's Complete Commentary on the Bible

      23 Give ye ear, and hear my voice; hearken, and hear my speech.   24 Doth the plowman plow all day to sow? doth he open and break the clods of his ground?   25 When he hath made plain the face thereof, doth he not cast abroad the fitches, and scatter the cummin, and cast in the principal wheat and the appointed barley and the rie in their place?   26 For his God doth instruct him to discretion, and doth teach him.   27 For the fitches are not threshed with a threshing instrument, neither is a cart wheel turned about upon the cummin; but the fitches are beaten out with a staff, and the cummin with a rod.   28 Bread corn is bruised; because he will not ever be threshing it, nor break it with the wheel of his cart, nor bruise it with his horsemen.   29 This also cometh forth from the LORD of hosts, which is wonderful in counsel, and excellent in working.

      This parable, which (like many of our Saviour's parables) is borrowed from the husbandman's calling, is ushered in with a solemn preface demanding attention, He that has ears to hear, let him hear, hear and understand, Isaiah 28:23; Isaiah 28:23.

      I. The parable here is plain enough, that the husbandman applies himself to the business of his calling with a great deal of pains and prudence, secundum artem--according to rule, and, as his judgment directs him, observes a method and order in his work. 1. In his ploughing and sowing: Does the ploughman plough all day to sow? Yes, he does, and he ploughs in hope and sows in hope,1 Corinthians 9:10. Does he open and break the clods? Yes, he does, that the land may be fit to receive the seed. And when he has thus made plain the face thereof does he not sow his seed, seed suitable to the soil? For the husbandman knows what grain is fit for clayey ground and what for sandy ground, and, accordingly, he sows each in its place--wheat in the principal place (so the margin reads it), for it is the principal grain, and was a staple commodity of Canaan (Ezekiel 27:17), and barley in the appointed place. The wisdom and goodness of the God of nature are to be observed in this, that, to oblige his creatures with a grateful variety of productions, he has suited to them an agreeable variety of earths. 2. In his threshing, Isaiah 28:27; Isaiah 28:28. This also he proportions to the grain that is to be threshed out. The fitches and the cummin, being easily got out of their husk or ear, are only threshed with a staff and a rod; but the bread-corn requires more force, and therefore that must be bruised with a threshing instrument, a sledge shod with iron, that was drawn to and fro over it, to beat out the corn; and yet he will not be ever threshing it, nor any longer than is necessary to loosen the corn from the chaff; he will not break it, or crush it, into the ground with the wheel of his cart, nor bruise it to pieces with his horsemen; the grinding of it is reserved for another operation. Observe, by the way, what pains are to be taken, not only for the earning, but for the preparing of our necessary food; and yet, after all, it is meat that perishes. Shall we then grudge to labour much more for the meat which endures to everlasting life? Bread-corn is bruised. Christ was so; it pleased the Lord to bruise him, that he might be the bread of life to us.

      II. The interpretation of the parable is not so plain. Most interpreters make it a further answer to those who set the judgments of God at defiance: "Let them know that as the husbandman will not be always ploughing, but will at length sow his seed, so God will not be always threatening, but will at length execute his threatenings and bring upon sinners the judgments they have deserved; but in wisdom, and in proportion to their strength, not that they may be ruined, but that they may be reformed and brought to repentance by them." But I think we may give this parable a greater latitude in the exposition of it. 1. In general, that God who gives the husbandman this wisdom is, doubtless, himself infinitely wise. It is God that instructs the husbandman to discretion, as his God,Isaiah 28:26; Isaiah 28:26. Husbandmen have need of discretion wherewith to order their affairs, and ought not undertake that business unless they do in some measure understand it; and they should by observation and experience endeavour to improve themselves in the knowledge of it. Since the king himself is served of the field, the advancing of the art of husbandry is a common service to mankind more than the cultivating of most other arts. The skill of the husbandman is from God, as every good and perfect gift is. This takes off somewhat of the weight and terror of the sentence passed on man for sin, that when God, in execution of it, sent man to till the ground, he taught him how to do it most to his advantage, otherwise, in the greatness of his folly, he might have been for ever tilling the sand of the sea, labouring to no purpose. It is he that gives men capacity for this business, an inclination to it, and a delight in it; and if some were not by Providence cut out for it, and mad to rejoice (as Issachar, that tribe of husbandmen) in their tents, notwithstanding the toil and fatigue of this business, we should soon want the supports of life. If some are more discreet and judicious in managing these or any other affairs than others are, God must be acknowledged in it; and to him husbandmen must seek for direction in their business, for they, above other men, have an immediate dependence upon the divine Providence. As to the other instance of the husbandman's conduct in threshing his corn, it is said, This also comes forth from the Lord of hosts,Isaiah 28:29; Isaiah 28:29. Even the plainest dictate of sense and reason must be acknowledged to come forth from the Lord of hosts. And, if it is from him that men do things wisely and discreetly, we must needs acknowledge him to be wise in counsel and excellent in working. God's working is according to his will; he never acts against his own mind, as men often do, and there is a counsel in his whole will: he is therefore excellent in working, because he is wonderful in counsel. 2. God's church is his husbandry, 1 Corinthians 3:9. If Christ is the true vine, his Father is the husbandman (John 15:1), and he is continually by his word and ordinances cultivating it. Does the ploughman plough all day, and break the clods of his ground, that it may receive the seed, and does not God by his ministers break up the fallow ground? Does not the ploughman, when the ground is fitted for the seed, cast in the seed in its proper soil? He does so, and so the great God sows his word by the hand of his ministers (Matthew 13:19), who are to divide the word of truth and give every one his portion. Whatever the soil of the heart is, there is some seed or other in the word proper for it. And, as the word of God, so the rod of God is thus wisely made use of. Afflictions are God's threshing-instruments, designed to loosen us from the world, to separate between us and our chaff, and to prepare us for use. And, as to these, God will make use of them as there is occasion; but he will proportion them to our strength; they shall be no heavier than there is need. If the rod and the staff will answer the end, he will not make use of his cart-wheel and his horsemen. And where these are necessary, as for the bruising of the bread-corn (which will not otherwise be got clean from the straw), yet he will not be ever threshing it, will not always chide, but his anger shall endure but for a moment; nor will he crush under his feet the prisoners of the earth. And herein we must acknowledge him wonderful in counsel and excellent in working.
