So the Lord didn’t kill Moses. When she said “husband who has forced me to spill my son’s blood,” she was talking about circumcision.
But Zipporah got a knife made out of flint. She circumcised her son with it. Then she touched Moses’ feet with the skin she had cut off. “Surely, you are a husband who has forced me to spill my son’s blood,” she said.
The Lord said to Aaron, “Go into the desert to see Moses.” So Aaron greeted Moses at the mountain of God and kissed him.
