21 And the Lord said to Moses, “When you go back to Egypt, see that you do before Pharaoh all the ^amiracles that I have put in your power. But ^bI will harden his heart, so that he will not let the people go.

9 Then the Lord said to Moses, ^c“Pharaoh will not listen to you, that ^dmy wonders may be multiplied in the land of Egypt.”

10 Moses and Aaron did all these wonders before Pharaoh, and the Lord ^ehardened Pharaoh’s heart, and he did not let the people of Israel go out of his land.
