19. And so the Lord said to Moses in Midian: "Go, and return to Egypt. For all those who sought your life have died."
20. Therefore, Moses took his wife and his sons, and he placed them upon a donkey, and he returned into Egypt, carrying the staff of God in his hand.
21. And the Lord said to him, as he was returning to Egypt: "See that you accomplish, in the sight of Pharaoh, all the wonders that I have placed in your hand. I will harden his heart, and he will not release the people.
22. And you shall say to him: 'Thus says the Lord: Israel is my firstborn son.
23. I have said to you: Release my son, so that he may serve me. And you were not willing to release him. Behold, I will put to death your firstborn son.' "
