Philippians 3:4-6

Amplified Bible

⁴ though I myself might have [some grounds for] confidence in the flesh [if I were pursuing salvation by works]. If anyone else thinks that he has reason to be confident in the flesh [that is, in his own efforts to achieve salvation], I have far more: ⁵ circumcised when I was eight days old, of the nation of Israel, of the tribe of Benjamin, a Hebrew of Hebrews [an exemplary Hebrew]; as to the [observance of the] Law, a Pharisee; ⁶ as to my zeal [for Jewish tradition], a persecutor of the church; and as to righteousness [supposed right living] which [my fellow Jews believe] is in the Law, I proved myself blameless.
