Philippians 3:5-7 NIV

[5] circumcised on the eighth day, of the people of Israel, of the tribe of Benjamin, a Hebrew of Hebrews; in regard to the law, a Pharisee; [6] as for zeal, persecuting the church; as for righteousness based on the law, faultless. [7] But whatever were gains to me I now consider loss for the sake of Christ.
