Exodus 4:21; Exodus 11:9–10

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.


Then the Lord said to Moses, cPharaoh 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.
