Romans 2:28-29 - New King James Version
28
For he is not a Jew who [is one] outwardly, nor [is] circumcision that which [is] outward in the flesh;
29
but [he is] a Jew who [is one] inwardly; and circumcision [is that] of the heart, in the Spirit, not in the letter; whose praise [is] not from men but from God.
