Exodus 10:13-19 ESV
So Moses stretched out his staff over the land of Egypt, and the LORD brought an east wind upon the land all that day and all that night. When it was morning, the east wind had brought the locusts. The locusts came up over all the land of Egypt and settled on the whole country of Egypt, such a dense swarm of locusts as had never been before, nor ever will be again. They covered the face of the whole land, so that the land was darkened, and they ate all the plants in the land and all the fruit of the trees that the hail had left. Not a green thing remained, neither tree nor plant of the field, through all the land of Egypt. Then Pharaoh hastily called Moses and Aaron and said, “I have sinned against the LORD your God, and against you. Now therefore, forgive my sin, please, only this once, and plead with the LORD your God only to remove this death from me.” So he went out from Pharaoh and pleaded with the LORD. And the LORD turned the wind into a very strong west wind, which lifted the locusts and drove them into the Red Sea. Not a single locust was left in all the country of Egypt.
