MSB(i)
28 A man is not a Jew because he is one outwardly, nor is circumcision only outward and physical.
29 No, a man is a Jew because he is one inwardly, and circumcision is a matter of the heart, by the Spirit, not by the written code. Such a man’s praise does not come from men, but from God.
3 1 What, then, is the advantage of being a Jew? Or what is the value of circumcision?
2 Much in every way. First of all, they have been entrusted with the very words of God.
