Romans 2:27-29

Revised Standard Version

²⁷ Then those who are physically uncircumcised but keep the law will condemn you who have the written code and circumcision but break the law. ²⁸ For he is not a real Jew who is one outwardly, nor is true circumcision something external and physical. ²⁹ He is a Jew who is one inwardly, and real circumcision is a matter of the heart, spiritual and not literal. His praise is not from men but from God.
