The Pharisees also with the Sadducees came, &c] Not from Jerusalem, as in Mt 15:1 but from the neighbouring places: these were Galilean Sadducees and Pharisees, of whom mention is made in the Misna ;"says ylylg yqwdu, "a Galilean Sadducee", (i.
e. one that was of the land of Galilee, as Bartenora on the place observes,) I complain of you Pharisees, because ye write the name of a ruler with the name of Moses, in a divorce; say the Pharisees, we complain of you Galilean Sadducees, that you write the name of a ruler with the name of God, in the same leaf:''but though these two sects could not agree in this, and in many other things, yet they could unite against Christ, to whom they bore an implacable hatred.
