'Circumcised' in the Bible

But not even Titus who was with me, being a Greek, was compelled to be circumcised:

As many as desire to make a fair show in the flesh, they compel you to be circumcised; only that they may not be persecuted for the cross of Christ.

For not even they who receive circumcision do themselves keep the law; but they desire to have you circumcised, that they may glory in your flesh.
