22 Then the Lord said to Moses, "Lift your hand toward the sky so hail may fall on the people, the livestock, and all the plants throughout the land of Egypt." 23 So Moses lifted his staff toward the sky, and the Lord sent thunder and hail, and lightning flashed toward the earth. The Lord sent a tremendous hailstorm against all the land of Egypt. 24 Never in all the history of Egypt had there been a storm like that, with such devastating hail and continuous lightning.

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.
