What kind of man was Paul according to his own Jewish credentials?

Les teaches that Paul was a religious fanatic, an Israelite, a Pharisee of the Pharisees, of the tribe of Benjamin, circumcised the eighth day. He was the epitome of a Judaistic Jew who practiced the Jewish religion to the hilt. This is the man who uses the commandment 'Thou shalt not covet' as the primary example of the law, showing that sin takes occasion by the commandment to work all manner of evil thinking. Without the law, old Adam was dead—not functioning in the spirit realm because he paid no attention to the law.
