“Beware of dogs, beware of evil workers, beware of the concision.”
King James Version (KJV)
3:2 Beware of dogs - Unclean, unholy, rapacious men. The title which the Jews usually gave the gentiles, he returns upon themselves. The concision - Circumcision being now ceased, the apostle will not call them the circumcision, but coins a term on purpose, taken from a Greek word used by the LXX, #Lev 21:5|, for such a cutting as God had forbidden.
Php 3:2 Beware of dogs. Those snarling and snapping like dogs. The Judaizing teachers, who so troubled the early churches, are meant. See Ga 1:6-9. Beware of evil workers. So called because by their false teaching about the necessity of circumcision they wrought evil. Beware of the concision. Applied to those who called themselves the circumcision. It means simply a "cutting", the class who were mutilated. It is contemptuous.
