Exodus 8:6-8

Young's Literal Translation

⁶ And Aaron stretcheth out his hand against the waters of Egypt, and the frog cometh up, and covereth the land of Egypt;

⁷ and the scribes do so with their flashings, and cause the frogs to come up against the land of Egypt.

⁸ And Pharaoh calleth for Moses and for Aaron, and saith, `Make supplication unto Jehovah, that he turn aside the frogs from me, and from my people, and I send the people away, and they sacrifice to Jehovah.'
