'Circumcised' in the Bible

But neither Titus, who was with me, being a Greek, was compelled to be circumcised:

Behold, I Paul say unto you, that if ye be circumcised, Christ shall profit you nothing.

For I testify again to every man that is circumcised, that he is a debtor to do the whole law.

As many as desire to make a fair shew in the flesh, they constrain you to be circumcised; only lest they should suffer persecution for the cross of Christ.

For neither they themselves who are circumcised keep the law; but desire to have you circumcised, that they may glory in your flesh.
