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.34And when Pharaoh saw that the rain and the hail and the thunders were ceased, he sinned yet more, and hardened his heart, he and his servants.

16Then Pharaoh called for Moses and Aaron in haste; and he said, I have sinned against the LORD your God, and against you.20But the LORD hardened Pharaoh's heart, so that he would not let the children of Israel go.
