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

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