Galatians 6:12-13, 17

Those who desire to make a good showing in the flesh try to compel you to be circumcised, simply so that they will not be persecuted for the cross of Christ. For those who are circumcised do not even keep the Law themselves, but they desire to have you circumcised so that they may boast in your flesh.

From now on let no one cause trouble for me, for I bear on my body the brand-marks of Jesus.
