Philippians 3:3-5

3For we who worship by the Spirit of God are the ones who are truly circumcised. We rely on what Christ Jesus has done for us. We put no confidence in human effort,

4though I could have confidence in my own effort if anyone could. Indeed, if others have reason for confidence in their own efforts, I have even more!

5I was circumcised when I was eight days old. I am a pure-blooded citizen of Israel and a member of the tribe of Benjamin—a real Hebrew if there ever was one! I was a member of the Pharisees, who demand the strictest obedience to the Jewish law.
