Genesi 17:14

And the uncircumcised man child whose flesh of his foreskin is not circumcised, that soul shall be cut off from his people; he hath broken my covenant.

Ver. 14. That soul shall be cut off.] From the commonwealth of Israel; so shall those be from benefit by Christ, that are uncircumcised in heart; as hateful to him as Goliath was to David. Pray, therefore, that God will thrust his holy hand into thy bosom, and pull off that abominable foreskin. He had much ado to forbear Moses, when he met him in the inn; and we know why. Exo 4:24-25
