Exodus 10:12-13

12And Jehovah said to Moses, Stretch out thy hand over the land of Egypt for the locusts, that they may come up over the land of Egypt, and eat every herb of the land — all that the hail hath left.

13And Moses stretched out his staff over the land of Egypt, and Jehovah brought an east wind on the land all that day and all that night. When it was morning, the east wind brought the locusts.
