Exodus 10:12-20

12And the LORD said to Moses, Stretch out thy hand over the land of Egypt for the locusts, that they may come upon the land of Egypt, and eat every herb of the land, even all that the hail hath left. 13And Moses stretched forth his rod over the land of Egypt, and the LORD brought an east wind upon the land all that day, and all that night; and when it was morning, the east wind brought the locusts. 14And the locusts went up over all the land of Egypt, and rested in all the land of Egypt: very grievous were they ; before them there were no such locusts as they, neither after them shall be such. 15For they covered the face of the whole earth, so that the land was darkened; and they ate every herb of the land, and all the fruit of the trees which the hail had left: and there remained not any green thing on the trees, or in the herbs of the field, through all the land of Egypt. 16Then Pharaoh called for Moses and Aaron in haste; and he said, I have sinned against the LORD your God, and against you.1 17Now therefore forgive, I pray thee, my sin only this once, and entreat the LORD your God, that he may take away from me this death only. 18And he went out from Pharaoh, and entreated the LORD. 19And the LORD turned a mighty strong west wind, which took away the locusts, and cast them into the Red sea; there remained not one locust in all the land of Egypt.2 20But the LORD hardened Pharaoh’s heart, so that he would not let the children of Israel go.
