Consequently he let go of him. At that time she said: ‘A bridegroom of blood,’ because of the circumcision.”

Zipporah’s unusual expression, “You are a bridegroom of blood to me,” was evidently made because circumcision involved a covenant. The author of that covenant was Jehovah God as here represented by His angel. Hence, in addressing Jehovah through his representative angel as a “bridegroom of blood,” Zipporah appears to have been, not speaking critically, but acknowledging her own submission now to the terms of that covenant. It was as if she had accepted a wifely position in the circumcision covenant, with Jehovah God as the husband. By this act of obedience to God’s proper requirement, the life of her son was no longer in danger.
