Joel 3:13 (b) The sickle is used as a type of GOD's judging and avenging wrath. The time came when He would endure Israel's rebellion no more. He exercised the same punishment upon the nations that persecuted Israel. One day He will cut down all the wicked nations of the earth, as we read in Revelation 14:14. GOD permits sinners to run their course, produce their evil fruit, and then He cuts them off, and the day of grace is ended.
