Philippians 3:2-6
Beware of the dogs; beware of the evil workers; beware of the false circumcision. For we are the circumcision, who worship God in the Spirit, and rejoice in Christ Jesus, and have no confidence in the flesh; though I myself might have confidence even in the flesh. If any other man thinks that he has confidence in the flesh, I yet more: circumcised the eighth day, of the stock of Israel, of the tribe of Benjamin, a Hebrew of Hebrews; concerning the law, a Pharisee; concerning zeal, persecuting the assembly; concerning the righteousness which is in the law, found blameless.
