Galatians 6:12-13

12Do not agree with those people who want to make you obey the Jewish rules. They say that you must let someone circumcise you. They want other people to think that they are important. They do not want to receive any trouble from others. They are afraid to teach that Christ's death on the cross is enough to save us.

13Even those men that someone has circumcised do not obey all the Jewish rules. They want to circumcise you only to make themselves seem important. They want to show that they have authority over your bodies.
