Exodus 8:7-9

7But the magicians did the same thing by their occult practices and brought frogs up onto the land of Egypt.

8Pharaoh summoned Moses and Aaron and said, “Appeal to the Lord to remove the frogs from me and my people. Then I will let the people go and they can sacrifice to the Lord.”

9Moses said to Pharaoh, “You may have the honor of choosing. When should I appeal on behalf of you, your officials, and your people, that the frogs be taken away from you and your houses, and remain only in the Nile?”
