'Circumcision' in the Bible

But not even Titus who was with me, being a Greek, was made to undergo circumcision:

But contrariwise, when they saw that the gospel of the uncircumcision was committed unto me, as the gospel of the circumcision was unto Peter;

(For he that wrought effectually in Peter to the apostleship of the circumcision, the same was mighty in me toward the Gentiles:)

And when James, Cephas, and John, who seemed to be pillars, perceived the grace that was given unto me, they gave to me and Barnabas the right hands of fellowship; that we should go unto the heathen, and they unto the circumcision.

For before that certain came from James, he did eat with the Gentiles: but when they were come, he withdrew and separated himself, fearing them which were of the circumcision.

Behold I, Paul, say to you that if you receive circumcision, Christ will be of no benefit to you.

And I testify again to every man who receives circumcision, that he is under obligation to keep the whole Law.

For in Jesus Christ neither circumcision availeth any thing, nor uncircumcision; but faith which worketh by love.

And I, brethren, if I yet preach circumcision, why do I yet suffer persecution? then is the offence of the cross ceased.

I would that they that unsettle you would even go beyond circumcision.

Those who want to make a good impression in public [before the Jews] try to compel you to be circumcised, just so they will escape being persecuted for [faithfulness to] 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.

For in Christ Jesus neither circumcision availeth any thing, nor uncircumcision, but a new creature.
