Exodus 9:27-30

27Then Pharaoh summoned Moses and Aaron. “This time I have sinned,” he said to them. “The Lord is in the right, and I and my people are in the wrong.

28Pray to the Lord, for we have had enough thunder and hail. I will let you go; you don’t have to stay any longer.”

29Moses replied, “When I have gone out of the city, I will spread out my hands in prayer to the Lord. The thunder will stop and there will be no more hail, so you may know that the earth is the Lord’s.

30But I know that you and your officials still do not fear the Lord God.”
