^21-23 God said to Moses, “When you get back to Egypt, be prepared: All the wonders that I will do through you, you’ll do before Pharaoh. But I will make him stubborn so that he will refuse to let the people go. Then you are to tell Pharaoh, ‘God’s Message: Israel is my son, my firstborn! I told you, “Free my son so that he can serve me.” But you refused to free him. So now I’m going to kill your son, your firstborn.’”

^24-26 On the journey back, as they camped for the night, God met Moses and would have killed him but Zipporah took a flint knife and cut off her son’s foreskin, and touched Moses’ member with it. She said, “Oh! You’re a bridegroom of blood to me!” Then God let him go. She used the phrase “bridegroom of blood” because of the circumcision.
