Exodus 10:12-13

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.
