Thematic Bible: Whose circumcision is made uncircumcision

For truly circumcision profits, if thou do the law: and if thou be a transgressor of the law, thy circumcision has become uncircumcision. Therefore if uncircumcision watch the justification of the law, shall not his uncircumcision be reckoned for circumcision? And shall not uncircumcision by nature, completing the law, judge thee, which by letter and circumcision a transgressor of the law?
