If any male is not circumcised in the flesh of his foreskin, that man will be cut off from his people; he has broken My covenant."
Genesis 17:14 In-Context
For the generations to come every male among you who is eight days old must be circumcised, including those born in your household or bought with money from a foreigner—those who are not your offspring.
Whether born in your household or bought with your money, they must be circumcised. My covenant in your flesh is to be an everlasting covenant.
Any uncircumcised male, who has not been circumcised in the flesh, will be cut off from his people; he has broken my covenant.”
God also said to Abraham, “As for Sarai your wife, you are no longer to call her Sarai; her name will be Sarah.
I will bless her and will surely give you a son by her. I will bless her so that she will be the mother of nations; kings of peoples will come from her.”
