23 And Moses stretched out his rod toward heaven; and the Lord sent thunder and hail, and fire darted to the ground. And the Lord rained hail on the land of Egypt. 24 So there was hail, and fire mingled with the hail, so very heavy that there was none like it in all the land of Egypt since it became a nation. 25 And the hail struck throughout the whole land of Egypt, all that was in the field, both man and beast; and the hail struck every herb of the field and broke every tree of the field. 26 Only in the land of Goshen, where the children of Israel were, there was no hail. 27 And Pharaoh sent and called for Moses and Aaron, and said to them, "I have sinned this time. The Lord is righteous, and my people and I are wicked. 28 Entreat the Lord, that there may be no more mighty thundering and hail, for it is enough. I will let you go, and you shall stay no longer." 29 So Moses said to him, "As soon as I have gone out of the city, I will spread out my hands to the Lord; the thunder will cease, and there will be no more hail, that you may know that the earth is the Lord's. 30 But as for you and your servants, I know that you will not yet fear the Lord God." 31 Now the flax and the barley were struck, for the barley was in the head and the flax was in bud. 32 But the wheat and the spelt were not struck, for they are late crops. 33 So Moses went out of the city from Pharaoh and spread out his hands to the Lord; then the thunder and the hail ceased, and the rain was not poured on the earth. 34 And when Pharaoh saw that the rain, the hail, and the thunder had ceased, he sinned yet more; and he hardened his heart, he and his servants.

Woful havoc this hail made: it killed both men and cattle; the corn above ground was destroyed, and that only preserved which as yet was not come up. The land of Goshen was preserved. God causes rain or hail on one city and not on another, either in mercy or in judgment. Pharaoh humbled himself to Moses. No man could have spoken better: he owns himself wrong; he owns that the Lord is righteous; and God must be justified when he speaks, though he speaks in thunder and lightning. Yet his heart was hardened all this while. Moses pleads with God: though he had reason to think Pharaoh would repent of his repentance, and he told him so, yet he promises to be his friend. Moses went out of the city, notwithstanding the hail and lightning which kept Pharaoh and his servants within doors. Peace with God makes men thunder-proof. Pharaoh was frightened by the tremendous judgment; but when that was over, his fair promises were forgotten. Those that are not bettered by judgments and mercies, commonly become worse.
