23 And Moses put out his rod to heaven: and the Lord sent thunder, and an ice-storm, and fire running down on the earth; the Lord sent an ice-storm on the land of Egypt. 24 So there was an ice-storm with fire running through it, coming down with great force, such as never was in all the land of Egypt from the time when it became a nation. 25 And through all the land of Egypt the ice-storm came down on everything which was in the fields, on man and on beast; and every green plant was crushed and every tree of the field broken. 26 Only in the land of Goshen, where the children of Israel were, there was no ice-storm. 27 Then Pharaoh sent for Moses and Aaron, and said to them, I have done evil this time: the Lord is upright, and I and my people are sinners. 28 Make prayer to the Lord; for there has been enough of these thunderings of God and this ice-storm; and I will let you go and will keep you no longer. 29 And Moses said, When I am gone outside the town, my hands will be stretched out to the Lord; the thunders and the ice-storm will come to an end, so that you may see that the earth is the Lord's. 30 But as for you and your servants, I am certain that even now the fear of the Lord God will not be in your hearts. 31 And the flax and the barley were damaged, for the barley was almost ready to be cut and the flax was in flower. 32 But the rest of the grain-plants were undamaged, for they had not come up. 33 So Moses went out of the town, and stretching out his hands made prayer to God: and the thunders and the ice-storm came to an end; and the fall of rain was stopped. 34 But when Pharaoh saw that the rain and the ice-storm and the thunders were ended, he went on sinning, and made his heart hard, he and his servants.

Commentary on Exodus 9:22-35

(Read Exodus 9:22-35)

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.
