Galatians 6:12-13

6:12 Those who want to make a good showing in external matters are trying to force you to be circumcised. They do so only to avoid being persecuted for the cross of Christ. 6:13 For those who are circumcised do not obey the law themselves, but they want you to be circumcised so that they can boast about your flesh.
