Exodus 10:12-15

12Then the Lord said to Moses, “Stretch out your hand over the land of Egypt for the locusts, so that they may come up on the land of Egypt and eat all the plants of the land, all that the hail has left.”

13So Moses stretched out his staff over the land of Egypt, and the Lord brought an east wind on the land all that day and all that night; when it was morning, the east wind had brought the [swarms of] locusts.

14The locusts came up over all the land of Egypt and settled down in the whole territory, a very dreadful mass of them; never before were there such locusts as these, nor will there ever be again.

15For they covered the [visible] surface of the land, so that the ground was darkened; and they ate every plant of the land and all the fruit of the trees which the hail had left. There remained not a green thing on the trees or the plants of the field throughout all the land of Egypt.
