RKJNT(i)
17 Behold, if you call yourself a Jew, and rely upon the law, and boast of your relationship with God,
18 And know his will, and approve the things that are excellent, being instructed out of the law;
19 And are confident that you yourself are a guide to the blind, a light for those who are in darkness,
20 An instructor for the foolish, a teacher of infants, having the embodiment of knowledge and truth in the law:
21 You, therefore, who teach others, do you not teach yourself? you who preach that a man should not steal, do you steal?
22 You who say a man should not commit adultery, do you commit adultery? you who abhor idols, do you rob temples?
23 You who make your boast in the law, do you dishonour God by breaking the law?
24 For as it is written, The name of God is blasphemed among the Gentiles because of you.
25 For circumcision is truly of value, if you keep the law: but if you are a breaker of the law, your circumcision has becomes uncircumcision.
26 Therefore, if the uncircumcised keeps the requirements of the law, shall not his uncircumcision be counted as circumcision?
27 And shall not the physically uncircumcised, if he keeps the law, judge you, who, though you have the letter of the law and circumcision, are transgressors of the law?
28 For he is not a Jew, who is one outwardly; neither is circumcision that which is outward in the flesh:
29 But he is a Jew, who is one inwardly; and circumcision is of the heart, by the spirit, and not by the letter; and his praise is not from men, but from God.
