Exodus 10:8

4 But if you refuse to let My people go, I will bring locusts into your territory tomorrow.

5 They will cover the face of the land so that no one can see it. They will devour whatever is left after the hail and eat every tree that grows in your fields.

6 They will fill your houses and the houses of all your officials and every Egyptian—something neither your fathers nor your grandfathers have seen since the day they came into this land.’” Then Moses turned and left Pharaoh’s presence.

7 Pharaoh’s officials asked him, “How long will this man be a snare to us? Let the people go, so that they may worship the LORD their God. Do you not yet realize that Egypt is in ruins?”

8 So Moses and Aaron were brought back to Pharaoh. “Go, worship the LORD your God,” he said. “But who exactly will be going?”

9 “We will go with our young and old,” Moses replied. “We will go with our sons and daughters, and with our flocks and herds, for we must hold a feast to the LORD.”

10 Then Pharaoh told them, “May the LORD be with you if I ever let you go with your little ones. Clearly you are bent on evil.

11 No, only the men may go and worship the LORD, since that is what you have been requesting.” And Moses and Aaron were driven from Pharaoh’s presence.

12 Then the LORD said to Moses, “Stretch out your hand over the land of Egypt, so that the locusts may swarm over it and devour every plant in the land—everything that the hail has left behind.”
