NSB(i)
17 If you are a Jew in name and are resting on the law and taking glory in God,
18 you know his will. You approve the things that are more excellent, being instructed out of the law.
19 And you have confidence that you are a leader of the blind, a light to those in darkness.
20 You are an instructor of the foolish, a teacher of babes, having the form of knowledge and of truth in the law.
21 You then who teach another, do you teach yourself? You who preach not to steal, do you steal?
22 You who say man should not commit adultery do you commit adultery? You who abhors idols do you rob temples?
23 You who boast in the law do you by transgression of the law dishonor God?
24 The name of God is blasphemed on your account among the nations, just as it is written. (Ezekiel 36:20, 21)
25 Circumcision is a benefit if you obey the law. But if you are a transgressor of the law your circumcision becomes uncircumcision.
26 If therefore someone not circumcised obeys the requirements of the law, shall not his uncircumcision be considered circumcision?
27 The uncircumcised person is by nature, fulfilling the law. He will judge you because you transgress the law with your written code and circumcision.
28 He is not a Jew who is one on the outside. Neither is circumcision that which is on the outside in the flesh.
29 But he is a Jew who is so on the inside with circumcision of the heart, in spirit, not in letter; whose praise is not of men, but of God.
