Exodus 8:1-6 NLT

1 Then the LORD said to Moses, "Go to Pharaoh once again and tell him, 'This is what the LORD says: Let my people go, so they can worship me.
2 If you refuse, then listen carefully to this: I will send vast hordes of frogs across your entire land from one border to the other.
3 The Nile River will swarm with them. They will come up out of the river and into your houses, even into your bedrooms and onto your beds! Every home in Egypt will be filled with them. They will fill even your ovens and your kneading bowls.
4 You and your people will be overwhelmed by frogs!'"
5 Then the LORD said to Moses, "Tell Aaron to point his shepherd's staff toward all the rivers, canals, and marshes of Egypt so there will be frogs in every corner of the land."
6 Aaron did so, and frogs covered the whole land of Egypt!
