Exodus 10:7-12

And Pharaoh's servants said unto him, How long shall this man be a snare unto us? let the men go, that they may serve the LORD their God: knowest thou not yet that Egypt is destroyed? And Moses and Aaron were brought again unto Pharaoh: and he said unto them, Go, serve the LORD your God: but who are they that shall go? And Moses said, We will go with our young and with our old, with our sons and with our daughters, with our flocks and with our herds will we go; for we must hold a feast unto the LORD. And he said unto them, Let the LORD be so with you, as I will let you go, and your little ones: look to it; for evil is before you. Not so: go now ye that are men, and serve the LORD; for that ye did desire. And they were driven out from Pharaoh's presence. And the LORD said unto Moses, Stretch out thine hand over the land of Egypt for the locusts, that they may come up upon the land of Egypt, and eat every herb of the land, even all that the hail hath left.
