Philippians 3:1-4 - Warning Against Evil Workers
1 Finally, my brothers, rejoice in the Lord. To write the same [things] to you [is] not troublesome to me, but [is] a safeguard for you.
2 Beware of the dogs, beware of the evil workers, beware of the mutilation. 3 For we are the circumcision, the ones who worship by the Spirit of God and boast in Christ Jesus and do not [put] confidence in the flesh, 4 although I [could] have confidence even in the flesh.
