Moses said to Pharaoh, "I leave it to you to set the time for me to pray for you, your officials, and your people, so that the frogs will be removed from you and your houses, remaining only in the Nile."
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.
