Exodus 10:12-15

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.
