Exodus 10:11

8 Then Moses and Aaron came in again before Pharaoh: and he said to them, Go and give worship to the Lord your God: but which of you are going?

9 And Moses said, We will go with our young and our old, with our sons and our daughters, with our flocks and our herds; for we are to keep a feast to the Lord.

10 And he said to them, May the Lord be with you, if I will let you and your little ones go! take care, for your purpose clearly is evil.

11 Not so; but let your males go and give worship to the Lord, as your desire is. This he said, driving them out from before him.

12 And the Lord said to Moses, Let your hand be stretched out over the land of Egypt so that the locusts may come up on the land for the destruction of every green plant in the land, even everything untouched by the ice-storm.

13 And Moses' rod was stretched out over the land of Egypt, and the Lord sent an east wind over the land all that day and all the night; and in the morning the locusts came up with the east wind.

14 And the locusts went up over all the land of Egypt, resting on every part of the land, in very great numbers; such an army of locusts had never been seen before, and never will be again.
