Romans 2:28

For he is not a Jew, which is one outwardly; neither is that circumcision, which is outward in the flesh:

For he is not a Jew who is one outwardly, neither is that circumcision which is outward in the flesh;

For he is not a Jew who is one outwardly; neither is that circumcision which is outward in the flesh:

For he is not a Jew who is `so' outwardly, neither `is' circumcision that which is outward in flesh;

A man is not a Jew because he is one outwardly, nor is circumcision only outward and physical.
