Jamieson, Fausset and Brown on Matthew 15:8

8. This people draweth nigh unto me with their mouth, &c.--By putting the commandments of men on a level with the divine requirements, their whole worship was rendered vain--a principle of deep moment in the service of God. "For," it is added in Mr 7:8, "laying aside the commandment of God, ye hold the tradition of men, as the washing of pots and cups; and many other such like things ye do." The drivelling nature of their multitudinous observances is here pointedly exposed, in contrast with the manly observance of "the commandment of God"; and when our Lord says, "Many other such like things ye do," it is implied that He had but given a specimen of the hideous treatment which the divine law received, and the grasping disposition which, under the mask of piety, was manifested by the ecclesiastics of that day.
