Exodus 8:7-9

7But the magicians did the same thing by their magic arts, and they also brought frogs up onto the land of Egypt.

8Pharaoh summoned Moses and Aaron and said, “Pray to the LORD to take the frogs away from me and my people. Then I will let your people go, that they may sacrifice to the LORD.”

9Moses said to Pharaoh, “You may have the honor over me. When shall I pray for you and your officials and your people that the frogs (except for those in the Nile) may be taken away from you and your houses?”
