Charles Ellicott Commentary Joel 3:13

"Put ye in the sickle; for the harvest is ripe: come, tread ye; for the winepress is full, the vats overflow; for their wickedness is great." — Joel 3:13 (ASV)

Put you in the sickle.— In the enthusiasm of his vision the prophet crowds together metaphors to intensify the description of the coming encounter between Jehovah and the enemies of His people. It is represented by the judgment seat, the harvest, and the vintage.

The hour of judgment has arrived—Jehovah Himself is judge. The harvest-time, which is the end of the world, has come—let the angel-reapers put in their sickle. In the wine-press the grapes are gathered in—let the labourers hasten to press the juice out with their feet.
