Exodus 8:7

4 The frogs will come up over you and your people and all your servants.

5 And the Lord said to Moses, Say to Aaron, Let the rod in your hand be stretched out over the streams and the waterways and the pools, causing frogs to come up on the land of Egypt.

6 And when Aaron put out his hand over the waters of Egypt, the frogs came up and all the land of Egypt was covered with them.

7 And the wonder-workers did the same with their secret arts, making frogs come up over the land of Egypt.

8 Then Pharaoh sent for Moses and Aaron and said, Make prayer to the Lord that he will take away these frogs from me and my people; and I will let the people go and make their offering to the Lord.

9 And Moses said, I will let you have the honour of saying when I am to make prayer for you and your servants and your people, that the frogs may be sent away from you and your houses, and be only in the Nile.

10 And he said, By tomorrow. And he said, Let it be as you say: so that you may see that there is no other like the Lord our God.
