22 Thou that sayest a man should not commit adultery, dost thou commit adultery? thou that abhorrest idols, dost thou commit sacrilege?
23 Thou that makest thy boast of the law, through breaking the law dishonourest thou God?
24 For the name of God is blasphemed among the Gentiles through you, as it is written.
25 For circumcision verily profiteth, if thou keep the law: but if thou be a breaker of the law, thy circumcision is made uncircumcision.
26 Therefore if the uncircumcision keep the righteousness of the law, shall not his uncircumcision be counted for circumcision?
27 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?
28 For he is not a Jew, which is one outwardly; neither is that circumcision, which is outward in the flesh:
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.
Romans 3
1 What advantage then hath the Jew? or what profit is there of circumcision?
2 Much every way: chiefly, because that unto them were committed the oracles of God.
3 For what if some did not believe? shall their unbelief make the faith of God without effect?
