Exodus 9:29

25 Throughout the land of Egypt, the hail struck down everything in the field, both man and beast; it beat down every plant of the field and stripped every tree.

26 The only place where it did not hail was in the land of Goshen, where the Israelites lived.

27 Then Pharaoh summoned Moses and Aaron. “This time I have sinned,” he said. “The LORD is righteous, and I and my people are wicked.

28 Pray to the LORD, for there has been enough of God’s thunder and hail. I will let you go; you do not need to stay any longer.”

29 Moses 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 that the earth is the LORD’s.

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

31 (Now the flax and barley were destroyed, since the barley was ripe and the flax was in bloom;

32 but the wheat and spelt were not destroyed, because they are late crops.)

33 Then Moses departed from Pharaoh, went out of the city, and spread out his hands to the LORD. The thunder and hail ceased, and the rain no longer poured down on the land.
