9:27And Pharaoh sent, and called for Moses and Aaron, and said unto them, I have sinned this time: the LORD is righteous, and I and my people are wicked.

10:16Then Pharaoh called for Moses and Aaron in haste; and he said, I have sinned against the LORD your God, and against you.

10:17Now therefore forgive, I pray thee, my sin only this once, and intreat the LORD your God, that he may take away from me this death only.
