Philippians 3:1-4 - Warning Against Evil Workers
1 Finally my brothers, rejoice in the Lord. To write the same things to you, to me indeed is not a bother, but for you it is a safeguard.
2 Beware of the dogs (impure men) (false teachers)! Beware of the evil workers! Beware of the mutilation of the body. 3 We are those with true circumcision who worship by the Spirit of God. We glory in Christ Jesus, and put no confidence in the flesh. 4 I might have confidence even in the flesh. If any other man thinks to have confidence in the flesh, I have more!
