“I will repay you
The years
That the swarming locust
Has eaten.
That is the hopper,
The destroyer,
The cutter,
My great army,
That I sent against you.”
Yahweh, via Joel, said that he was going to repay and restore things like they were before the locust plague hit them. Then he enumerated, as earlier in chapter 1, the various forms of the locust grasshoppers, the hoppers, the destroyers, and the cutters. However, it was clear here that Yahweh had sent this army of locusts against them.
