21. And the lord told Moses, “When you arrive back in Egypt, go to Pharaoh and perform all the miracles I have empowered you to do. But I will harden his heart so he will refuse to let the people go.
22. Then you will tell him, ‘This is what the lord says: Israel is my firstborn son.
23. I commanded you, “Let my son go, so he can worship me.” But since you have refused, I will now kill your firstborn son!’”
24. On the way to Egypt, at a place where Moses and his family had stopped for the night, the lord confronted him and was about to kill him.
25. But Moses’ wife, Zipporah, took a flint knife and circumcised her son. She touched his feet with the foreskin and said, “Now you are a bridegroom of blood to me.”
26. (When she said “a bridegroom of blood,” she was referring to the circumcision.) After that, the lord left him alone.
