13 Then the Lord said to Moses, “Get up early in the morning and present yourself to Pharaoh. Tell him: This is what Yahweh, the God of the Hebrews says: Let My people go, so that they may worship Me. 14 Otherwise, I am going to send all My plagues against you, your officials, and your people. Then you will know there is no one like Me in all the earth. 15 By now I could have stretched out My hand and struck you and your people with a plague, and you would have been obliterated from the earth. 16 However, I have let you live for this purpose: to show you My power and to make My name known in all the earth. 17 You are still acting arrogantly against My people by not letting them go. 18 Tomorrow at this time I will rain down the worst hail that has ever occurred in Egypt from the day it was founded until now. 19 Therefore give orders to bring your livestock and all that you have in the field into shelters. Every person and animal that is in the field and not brought inside will die when the hail falls on them.” 20 Those among Pharaoh’s officials who feared the word of the Lord made their servants and livestock flee to shelters, 21 but those who didn’t take the Lord’s word seriously left their servants and livestock in the field.
22 Then the Lord said to Moses, “Stretch out your hand toward heaven and let there be hail throughout the land of Egypt—on man and beast and every plant of the field in the land of Egypt.” 23 So Moses stretched out his staff toward heaven, and the Lord sent thunder and hail. Lightning struck the earth, and the Lord rained hail on the land of Egypt. 24 The hail, with lightning flashing through it, was so severe that nothing like it had occurred in the land of Egypt since it had become a nation. 25 Throughout the land of Egypt, the hail struck down everything in the field, both man and beast. The hail beat down every plant of the field and shattered every tree in the field. 26 The only place it didn’t hail was in the land of Goshen where the Israelites were.
27 Pharaoh sent for Moses and Aaron. “I have sinned this time,” he said to them. “Yahweh is the Righteous One, and I and my people are the guilty ones. 28 Make an appeal to Yahweh. There has been enough of God’s thunder and hail. I will let you go; you don’t need to stay any longer.”
29 Moses said to him, “When I have left the city, I will extend my hands to Yahweh. The thunder will cease, and there will be no more hail, so that you may know the earth belongs to Yahweh. 30 But as for you and your officials, I know that you still do not fear Yahweh our God.”
31 The flax and the barley were destroyed because the barley was ripe and the flax was budding, 32 but the wheat and the spelt were not destroyed since they are later crops.
33 Moses went out from Pharaoh and the city, and extended his hands to the Lord. Then the thunder and hail ceased, and rain no longer poured down on the land. 34 When Pharaoh saw that the rain, hail, and thunder had ceased, he sinned again and hardened his heart, he and his officials. 35 So Pharaoh’s heart hardened, and he did not let the Israelites go, as the Lord had said through Moses.
