All therefore, &c.— The morality of the Pharisees, as appears from many examples mentioned in the Gospel, was of a very loose kind; and as for the traditions which they taught, they often made void the law of God altogether. It is not therefore to be thought, that Jesus would recommend the doctrines and precepts of the Pharisees without exception; and for this reason we must limit the general expressions here made use of, by what goes before in this discourse; thus, "While these men sit in Moses' seat, while they rightly explain the doctrines and precepts of the law, be sure to obey them; but by no means imitate their practices."
