Philippians 3:5-6

3:5 I was circumcised on the eighth day, from the people of Israel and the tribe of Benjamin, a Hebrew of Hebrews. I lived according to the law as a Pharisee. 3:6 In my zeal for God I persecuted the church. According to the righteousness stipulated in the law I was blameless.

Philippians 3:9

3:9 and be found in him, not because I have my own righteousness derived from the law, but because I have the righteousness that comes by way of Christ’s faithfulness – a righteousness from God that is in fact based on Christ’s faithfulness.
