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.
