Galatians 6:11-14

See with how large letters I write unto you with mine own hand. 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. But far be it from me to glory, save in the cross of our Lord Jesus Christ, through which the world hath been crucified unto me, and I unto the world.
