Romans 2:27-29

Young's Literal Translation

²⁷ and the uncircumcision, by nature, fulfilling the law, shall judge thee who, through letter and circumcision, [art] a transgressor of law.

²⁸ For he is not a Jew who is [so] outwardly, neither [is] circumcision that which is outward in flesh;

²⁹ but a Jew [is] he who is [so] inwardly, and circumcision [is] of the heart, in spirit, not in letter, of which the praise is not of men, but of God.
