Exodus 9:27-30

Then Pharaoh quickly summoned Moses and Aaron. “This time I have sinned,” he confessed. “The LORD is the righteous one, and my people and I are wrong. Please beg the LORD to end this terrifying thunder and hail. We’ve had enough. I will let you go; you don’t need to stay any longer.” “All right,” Moses replied. “As soon as I leave the city, I will lift my hands and pray to the LORD. Then the thunder and hail will stop, and you will know that the earth belongs to the LORD. But I know that you and your officials still do not fear the LORD God.”
