'Uncircumcision' in the Bible

For circumcision indeed profits if thou keep the law; but if thou be a law-transgressor, thy circumcision is become uncircumcision.

If therefore the uncircumcision keep the requirements of the law, shall not his uncircumcision be reckoned for circumcision,

and uncircumcision by nature, fulfilling the law, judge thee, who, with letter and circumcision, art a law-transgressor?

since indeed it is one God who shall justify the circumcision on the principle of faith, and uncircumcision by faith.

Does this blessedness then rest on the circumcision, or also on the uncircumcision? For we say that faith has been reckoned to Abraham as righteousness.

How then has it been reckoned? when he was in circumcision, or in uncircumcision? Not in circumcision, but in uncircumcision.

And he received the sign of circumcision as seal of the righteousness of faith which he had being in uncircumcision, that he might be the father of all them that believe being in uncircumcision, that righteousness might be reckoned to them also;

and father of circumcision, not only to those who are of the circumcision, but to those also who walk in the steps of the faith, during uncircumcision, of our father Abraham.
