Exodus 10:12-13

12Then the Lord said to Moses, ‘Lift up your hand over the country of Egypt. Then locusts will fly all over the land. They will eat every plant that grows in the ground. They will eat everything that the hail has not destroyed.’

13So Moses lifted up his stick over the country of Egypt. Then the Lord caused an east wind to blow across the land, for the whole day and the whole night. In the morning, the east wind had brought the locusts.
