Look out for the dogs, look out for the evildoers, look out for those who mutilate the flesh. (Philippians 3:2, ESV)Dogs and evildoers... Sounds harsh, but who is he talking about? We will find out over the next few verses, but there is a little play on words here that is a hint... "... those who mutilate the flesh" is very similar (in the Greek) to the phrasing for one getting circumcised.
For what is our hope or joy or crown of boasting before our Lord Jesus at his coming? Is it not you? (1 Thessalonians 2:19 -- ESV) Three things mentioned here... "hope" ... "joy" ... "crown of boasting" ... Hope - What does Paul have his sights set on? Joy - What is it that brings Paul joy? Crown of Boasting - That Olympic Wreath of Glory that is placed on his head? It is these people. It is his children in the faith. They are Paul's Hope and Joy and Crown of Glory when Jesus returns.
