Exodus 9:27-30

So Pharaoh sent, called for Moses and Aaron and said to them, “I have sinned this time. ADONAI is righteous, while I and my people are wicked. Pray to ADONAI—there has been enough of God’s thunders and hail! I will let you go. You don’t have to stay any longer.” Moses said to him, “As soon as I am gone out of the city, I will stretch out my hands to ADONAI. The thunder will cease and there will be no more hail—so you may know that the earth is ADONAI’s. But as for you and your servants, I know that you do not yet fear ADONAI Elohim.”
