Philippians 3:5-6

I was born a true Hebrew of the heritage of Israel as the son of a Jewish man from the tribe of Benjamin. I was circumcised eight days after my birth and was raised in the strict tradition of Orthodox Judaism, living a separated and devout life as a Pharisee. And concerning the righteousness of the Torah, no one surpassed me; I was without a peer. Furthermore, as a fiery defender of the truth, I persecuted the messianic believers with religious zeal.
