Galatians 6:12-13

As many as desire to make a fair show in the flesh, etc. To comply with the worldly demands. They desire to have you circumcised, because, if you are not, and they fellowship you, the Jews will persecute them. For neither they themselves who are circumcised keep the law. They do not keep the law in all its details, but want to bring you under it that they may boast of their Gentile proselytes.

That they may glory in your flesh. Glory because circumcision has made marks in your flesh.
