'Uncircumcision' in the Bible

For circumcision verily profiteth, if thou keep the law: but if thou be a breaker of the law, thy circumcision is made uncircumcision.

Therefore if the uncircumcision keep the righteousness of the law, shall not his uncircumcision be counted for circumcision?

And shall not uncircumcision which is by nature, if it fulfil the law, judge thee, who by the letter and circumcision dost transgress the law?

Seeing it is one God, which shall justify the circumcision by faith, and uncircumcision through faith.

Cometh this blessedness then upon the circumcision only, or upon the uncircumcision also? for we say that faith was reckoned to Abraham for righteousness.

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