¹⁹ And the Lord said to Moses in Mid′ian, “Go back to Egypt; for all the men who were seeking your life are dead.” ²⁰ So Moses took his wife and his sons and set them on an ass, and went back to the land of Egypt; and in his hand Moses took the rod of God.

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