Paul and Jewish circumcision (chapter 3)

Paul had confidence in human flesh, since he had been circumcised on the eighth day of his life.  He was a member of the people of Israel from the tribe of Benjamin.  He was a Hebrew born of Hebrews.  He was a follower of the law as a zealous Pharisee.  He even persecuted the early Christian church communities.  He followed the law blamelessly and righteously.  He was a true circumcised Jewish person, more so than other Jewish people.
