Romans 2:27 BBE

²⁵  It is true that circumcision is of use if you keep the law, but if you go against the law it is as if you had it not.

²⁶  If those who have not circumcision keep the rules of the law, will it not be credited to them as circumcision?

²⁷  And they, by their keeping of the law without circumcision, will be judges of you, by whom the law is broken though you have the letter of the law and circumcision.

²⁸  The true Jew is not one who is only so publicly, and circumcision is not that which may be seen in the flesh:

²⁹  But he is a Jew who is a secret one, whose circumcision is of the heart, in the spirit and not in the letter; whose praise is not from men, but from God.
