20 And Moses took his wife and his sons and had them ride on the donkey, and he returned to the land of Egypt, and Moses took the staff of God in his hand.
21 And Yahweh said to Moses, “When you go to return to Egypt, see all of the wonders that I have put in your hand, and do them before Pharaoh, and I myself will harden his heart, and he will not release the people.
22 And you must say to Pharaoh, ‘Thus says Yahweh, “Israel is my son, my firstborn.”
23 And I said to you, “Release my son and let him serve me,” but you refused to release him. Look, I am about to kill your son, your firstborn.’ ”
24 And on the way, at the place of overnight lodging, Yahweh encountered him and sought to kill him.
25 But Zipporah took a flint knife, and she cut off the foreskin of her son, and she touched his feet, and she said, “Yes, you are a bridegroom of blood to me.”
26 And he left him alone. At that time she said, “A bridegroom of blood,” because of the circumcision.
