'Circumcision' in the Bible

but contrariwise, when they saw that I had been intrusted with the gospel of the uncircumcision, even as Peter with the gospel of the circumcision

(for he that wrought for Peter unto the apostleship of the circumcision wrought for me also unto the Gentiles);

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

For before that certain came from James, he ate with the Gentiles; but when they came, he drew back and separated himself, fearing them that were of the circumcision.

Behold, I Paul say unto you, that, if ye receive circumcision, Christ will profit you nothing.

Yea, I testify again to every man that receiveth circumcision, that he is a debtor to do the whole law.

For in Christ Jesus neither circumcision availeth anything, nor uncircumcision; but faith working through love.

But I, brethren, if I still preach circumcision, why am I still persecuted? then hath the stumbling-block of the cross been done away.

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

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 neither is circumcision anything, nor uncircumcision, but a new creature.
