Galatians 6:12-13, 17

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 even the circumcised [Jews] themselves do not [really] keep the Law, but they want to have you circumcised so that they may boast in your flesh [that is, in the fact that they convinced you to be circumcised].

From now on let no one trouble me [by making it necessary for me to justify my authority as an apostle, and the absolute truth of the gospel], for I bear on my body the branding-marks of Jesus [the wounds, scars, and other outward evidence of persecutions—these testify to His ownership of me].
