Romans 2:25, 28~29
Romans 2:25 For circumcision verily profiteth, if thou keep the law: but if thou be a breaker of the law, thy circumcision is made uncircumcision. 5 I MC VC
Romans 2:28 For he is not a Jew, which is one outwardly; neither is that circumcision, which is outward in the flesh: 5 I MC VC
Romans 2:29 But he is a Jew, which is one inwardly; and circumcision is that of the heart, in the spirit, and not in the letter; whose praise is not of men, but of God. 7 I MC VC
