17If then you are called a Jew and rest upon the law and boast in God18and know the will and test the things that surpass while being instructed from the law19you have persuaded yourself both to be a guide of the blind and a light to those who are in darkness20an instructor of the foolish, a teacher of children, possessing the form of knowledge and of the truth in the law21Therefore, while teaching another you do not teach yourself; while preaching not to steal you steal22while saying not to commit adultery you commit adultery; while abhorring the idols you despoil temples23You who boast in the law through the transgression of the law dishonor God24For the name of God is blasphemed among the Gentiles because of you, as it has been written25Circumcision on the other hand profits if you practice the law; but if you are a transgressor of the law, your circumcision has become uncircumcision26Therefore if the uncircumcision keeps the righteous acts of the law, will not its uncircumcision be counted as circumcision27And the uncircumcision by nature, which finishes the law, will judge you who are a transgressor of the law through the written code and circumcision28For the one who is a Jew outwardly is not a Jew, nor is circumcision that which is outward in the flesh29but the one who is a Jew in secret, and circumcision of the heart in the Spirit, not in the letter, whose praise is not from humans but from God
