Exodus 9:27-30

27Pharaoh sent for Moses and Aaron. “I have sinned this time,” he said to them. “The Lord is the righteous one, and I and my people are the guilty ones.

28Make an appeal to the Lord. There has been enough of God’s thunder and hail. I will let you go; you don’t need to stay any longer.”

29Moses said to him, “When I have left the city, I will spread out my hands to the Lord. The thunder will cease, and there will be no more hail, so that you may know the earth belongs to the Lord.

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