John Wesley on Philippians 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.
