Romans 2:28-29 For he is not a Jew, who is one outwardly; neither is circumcision that which is outward in the flesh:

RKJNT⁽ⁱ⁾ ²⁸ For he is not a Jew, who is one outwardly; neither is circumcision that which is outward in the flesh: ²⁹ But he is a Jew, who is one inwardly; and circumcision is of the heart, by the spirit, and not by the letter; and his praise is not from men, but from God.
