Exodus 4:25-26

New International Version

²⁵ But Zipporah^(A) took a flint knife, cut off her son’s foreskin^(B) and touched Moses’ feet with it.^[a] “Surely you are a bridegroom of blood to me,” she said. ²⁶ So the Lord let him alone. (At that time she said “bridegroom of blood,” referring to circumcision.)
