Exodus 10:4-12

For if you refuse to let my people go, behold, tomorrow I will bring locusts into your country, and they shall cover the face of the land, so that no one can see the land. And they shall eat what is left to you after the hail, and they shall eat every tree of yours that grows in the field, and they shall fill your houses and the houses of all your servants and of all the Egyptians, as neither your fathers nor your grandfathers have seen, from the day they came on earth to this day.’” Then he turned and went out from Pharaoh. Then Pharaoh’s servants said to him, “How long shall this man be a snare to us? Let the men go, that they may serve the LORD their God. Do you not yet understand that Egypt is ruined?” So Moses and Aaron were brought back to Pharaoh. And he said to them, “Go, serve the LORD your God. But which ones are to go?” Moses said, “We will go with our young and our old. We will go with our sons and daughters and with our flocks and herds, for we must hold a feast to the LORD.” But he said to them, “The LORD be with you, if ever I let you and your little ones go! Look, you have some evil purpose in mind. No! Go, the men among you, and serve the LORD, for that is what you are asking.” And they were driven out from Pharaoh’s presence. Then the LORD said to Moses, “Stretch out your hand over the land of Egypt for the locusts, so that they may come upon the land of Egypt and eat every plant in the land, all that the hail has left.”
