The sending of spies to ascertain the strength or state of an enemy's country was known as early as Genesis 42 , when Joseph treated his brethren as such. Twelve were sent by Moses to search out the land of Palestine, the adoption of this means being first desired by the people, and afterwards ordered by God. Only two brought up a faithful report, and had faith in God that He would give them possession. Numbers 13 . Two were also sent by Joshua, who were hidden by Rahab. Joshua 2; Joshua 6:23; Hebrews 11:31 . David and Absalom both used this stratagem. 1 Samuel 26:4; 2 Samuel 15:10; cf. Judges 1:24 .
Those are called 'spies' whom the rulers of Israel sent to entrap the Lord. They were secret agents who, by feigning themselves just men, hoped to catch the Lord in His replies; but they were themselves put to shame, and confounded by His wisdom. Luke 20:20 .
