The Lord said to Moses, “When you go to return into Egypt, see that you do all those wonders before Pharaoh, which I have put in your hand, but I will harden his heart, so that he shall not let the people go.
And the river will swarm with frogs, which shall go up and come into your house, and into your bedchamber, and on your bed, and into the houses of your servants, and on your people, and into your ovens, and into your kneading troughs.
Moses said to Pharaoh, “Be pleased to command me: When shall I entreat for you, your servants, and your people, to destroy the frogs from you and your houses, that they may remain in the river only?”
