Exodus 9:27-35

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.”

31The flax and the barley were destroyed because the barley was ripe and the flax was budding,

32but the wheat and the spelt were not destroyed since they are later crops.

33Moses left Pharaoh and the city, and spread out his hands to the Lord. Then the thunder and hail ceased, and rain no longer poured down on the land.

34When Pharaoh saw that the rain, hail, and thunder had ceased, he sinned again and hardened his heart, he and his officials.

35So Pharaoh’s heart was hard, and he did not let the Israelites go, as the Lord had said through Moses.
