Romans 2:29 YLT

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.
