Exodus 8:5-8King James Version (KJV)
5 And the Lord spake unto Moses, Say unto Aaron, Stretch forth thine hand with thy rod over the streams, over the rivers, and over the ponds, and cause frogs to come up upon the land of Egypt.
6 And Aaron stretched out his hand over the waters of Egypt; and the frogs came up, and covered the land of Egypt.
7 And the magicians did so with their enchantments, and brought up frogs upon the land of Egypt.
8 Then Pharaoh called for Moses and Aaron, and said, Intreat the Lord, that he may take away the frogs from me, and from my people; and I will let the people go, that they may do sacrifice unto the Lord.
