18. and knowest the will, and discerningly approvest the things that are more excellent, being instructed out of the law;
19. and hast confidence that thou thyself art a leader of the blind, a light of those who are in darkness,
20. an instructor of the foolish, a teacher of babes, having the form of knowledge and of truth in the law:
21. thou then that teachest another, dost thou not teach thyself? thou that preachest not to steal, dost thou steal?
22. thou that sayest man should not commit adultery, dost thou commit adultery? thou that abhorrest idols, dost thou commit sacrilege?
23. thou who boastest in law, dost thou by transgression of the law dishonour God?
24. For the name of God is blasphemed on your account among the nations, according as it is written.
25. For circumcision indeed profits if thou keep the law; but if thou be a law-transgressor, thy circumcision is become uncircumcision.
26. If therefore the uncircumcision keep the requirements of the law, shall not his uncircumcision be reckoned for circumcision,
27. and uncircumcision by nature, fulfilling the law, judge thee, who, with letter and circumcision, art a law-transgressor?
28. For he is not a Jew who is one outwardly, neither that circumcision which is outward in flesh;
29. but he is a Jew who is so inwardly; and circumcision, of the heart, in spirit, not in letter; whose praise is not of men, but of God.
