Exodus 10:4

1 Then the LORD said to Moses, “Go to Pharaoh, for I have hardened his heart and the hearts of his officials, that I may perform these miraculous signs of Mine among them,

2 and that you may tell your children and grandchildren how severely I dealt with the Egyptians when I performed miraculous signs among them, so that all of you may know that I am the LORD.”

3 So Moses and Aaron went to Pharaoh and told him, “This is what the LORD, the God of the Hebrews, says: ‘How long will you refuse to humble yourself before Me? Let My people go, so that they may worship Me.

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?”
