Exodus 8:8-10

8:8 Then Pharaoh summoned Moses and Aaron and said, “Pray to the Lord that he may take the frogs away from me and my people, and I will release the people that they may sacrifice to the Lord.” 8:9 Moses said to Pharaoh, “You may have the honor over me – when shall I pray for you, your servants, and your people, for the frogs to be removed from you and your houses, so that they will be left only in the Nile?” 8:10 He said, “Tomorrow.” And Moses said, “It will be as you say, so that you may know that there is no one like the Lord our God.
