'Circumcision' in the Bible

You were also circumcised in Him with a circumcision not done with hands, by putting off the body of flesh, in the circumcision of the Messiah.

In Christ there is not Greek and Jew, circumcision and uncircumcision, barbarian, Scythian, slave and free; but Christ is all and in all.

and so does Jesus who is called Justus. These alone of the circumcision are my coworkers for the kingdom of God, and they have been a comfort to me.
