19 The religious experts said to Pharaoh, "This is something only God could do!" But Pharaoh was stubborn, and he wouldn’t listen to them, just as the Lord had said.
20 The Lord said to Moses, "Get up early in the morning and confront Pharaoh as he goes out to the water. Say to him, This is what the Lord says: Let my people go so that they can worship me.
21 If you refuse to let my people go, I’ll send swarms of insects on you, your officials, your people, and your houses. All Egyptian houses will be filled with swarms of insects and also the ground that they cover.
22 But on that day I’ll set apart the land of Goshen, where my people live. No swarms of insects will come there so you will know that I, the Lord, am in this land.
23 I’ll put a barrier between my people and your people. This sign will happen tomorrow."
24 The Lord did this. Great swarms of insects came into the houses of Pharaoh and his officials and into the whole land of Egypt. The land was ruined by the insects.
25 Then Pharaoh called in Moses and Aaron and said, "Go, offer sacrifices to your God within the land."
