Exodus 8:7-9

New Revised Standard Version, Anglicised

⁷ But the magicians did the same by their secret arts, and brought frogs up on the land of Egypt.

⁸ Then Pharaoh called Moses and Aaron, and said, ‘Pray to the Lord to take away the frogs from me and my people, and I will let the people go to sacrifice to the Lord.’ ⁹ Moses said to Pharaoh, ‘Kindly tell me when I am to pray for you and for your officials and for your people, that the frogs may be removed from you and your houses and be left only in the Nile.’
