Romans 2:29 ASV

²⁷  and shall not the uncircumcision which is by nature, if it fulfil the law, judge thee, who with the letter and circumcision art a transgressor of the law?

²⁸  For he is not a Jew who is one outwardly; neither is that circumcision which is outward in the flesh:

²⁹  but he is a Jew who is one inwardly; and circumcision is that of the heart, in the spirit not in the letter; whose praise is not of men, but of God.
