On the way, at a place where they spent the night, the LORD met him and tried to kill him. But Zipporah took a flint and cut off her son's foreskin, and touched Moses' feet with it, and said, "Truly you are a bridegroom of blood to me!" So he let him alone. It was then she said, "A bridegroom of blood by circumcision." (Exodus 4:24-26, NRSV)
At a lodging place on the way, the Lord met Moses and was about to kill him. But Zipporah took a flint knife, cut off her son’s foreskin and touched Moses’ feet with it. “Surely you are a bridegroom of blood to me,” she said. So the Lord let him alone. (At that time she said “bridegroom of blood,” referring to circumcision.) (NIV)
As Moses and his family were traveling along and had stopped for the night, Jehovah appeared to Moses and threatened to kill him. Then Zipporah his wife took a flint knife and cut off the foreskin of her young son’s penis, and threw it against Moses’ feet, remarking disgustedly, “What a blood-smeared husband you’ve turned out to be!”
Then God left him alone. (TLB)
