Phil 3:2-6

2 Watch out for those people who behave like dogs! They are evil and want to do more than just circumcise you. 3 But we are the ones who are truly circumcised, because we worship by the power of God's Spirit and take pride in Christ Jesus. We don't brag about what we have done, 4 although I could. Others may brag about themselves, but I have more reason to brag than anyone else. 5 I was circumcised when I was eight days old, and I am from the nation of Israel and the tribe of Benjamin. I am a true Hebrew. As a Pharisee, I strictly obeyed the Law of Moses. 6 And I was so eager I even made trouble for the church. I did everything the Law demands in order to please God.
