Exodus 8:6-8

New Revised Standard Version, Anglicised

⁶ So Aaron stretched out his hand over the waters of Egypt; and the frogs came up and covered the land of Egypt. 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.’
