Romans 2:28-29

Amplified Bible, Classic Edition

²⁸ For he is not a [real] Jew who is only one outwardly and publicly, nor is [true] circumcision something external and physical.

²⁹ But he is a Jew who is one inwardly, and [true] circumcision is of the heart, a spiritual and not a literal [matter]. His praise is not from men but from God.
