Most of the Salem believers had practiced circumcision, though it had never been made obligatory by Melchizedek. Now Abraham had always so opposed circumcision that on this occasion he decided to solemnize the event by formally accepting this rite in token of the ratification of the Salem covenant.
Close in meaning, found by a language model. A match does not mean the teachings are the same.
Is this blessing then pronounced only on the circumcised, or on the uncircumcised also? For we say that faith was accounted to Abraham for righteousness. How then was it counted? When he was in circumcision, or in uncircumcision? Not in circumcision, but in uncircumcision. He received the sign of circumcision, a seal of the righteousness of the faith which he had while he was in uncircumcision, that he might be the father of all those who believe, though they might be in uncircumcision, that righteousness might also be accounted to them. He is the father of circumcision to those who not only are of the circumcision, but who also walk in the steps of that faith of our father Abraham, which he had in uncircumcision.
God said to Abraham, “As for you, you shall keep my covenant, you and your offspring after you throughout their generations. This is my covenant, which you shall keep, between me and you and your offspring after you. Every male among you shall be circumcised. You shall be circumcised in the flesh of your foreskin. It will be a token of the covenant between me and you. He who is eight days old shall be circumcised among you, every male throughout your generations, he who is born in the house, or bought with money from any foreigner who is not of your offspring. He who is born in your house, and he who is bought with your money, must be circumcised. My covenant shall be in your flesh for an everlasting covenant. The uncircumcised male who is not circumcised in the flesh of his foreskin, that soul shall be cut off from his people. He has broken my covenant.”
When he finished talking with him, God went up from Abraham. Abraham took Ishmael his son, all who were born in his house, and all who were bought with his money: every male among the men of Abraham’s house, and circumcised the flesh of their foreskin in the same day, as God had said to him. Abraham was ninety-nine years old when he was circumcised in the flesh of his foreskin. Ishmael, his son, was thirteen years old when he was circumcised in the flesh of his foreskin. In the same day both Abraham and Ishmael, his son, were circumcised. All the men of his house, those born in the house, and those bought with money from a foreigner, were circumcised with him.
