And Pharaoh sent, and called for Moses and Aaron, and said unto them, I {g} have sinned this time: the LORD is righteous, and I and my people are wicked.

(g) The wicked confess their sins to their condemnation, but they cannot believe to obtain remission.

Jamieson-Fausset-Brown Bible Commentary

27-35. Pharaoh sent, and called for Moses and Aaron, and said unto them, I have sinned-This awful display of divine displeasure did seriously impress the mind of Pharaoh, and, under the weight of his convictions, he humbles himself to confess he has done wrong in opposing the divine will. At the same time he calls for Moses to intercede for cessation of the calamity. Moses accedes to his earnest wishes, and this most awful visitation ended. But his repentance proved a transient feeling, and his obduracy soon became as great as before.

Matthew Henry's Concise Commentary

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.
