Exodus 4:24-26

4:24 Now on the way, at a place where they stopped for the night, the Lord met Moses and sought to kill him. 4:25 But Zipporah took a flint knife, cut off the foreskin of her son and touched it to Moses’ feet, and said, “Surely you are a bridegroom of blood to me.” 4:26 So the Lord let him alone. (At that time she said, “A bridegroom of blood,” referring to the circumcision.)
