Full well - These words are capable of different interpretations. Some read them as a question: "Do ye do well in rejecting?" etc. Others suppose they mean "skillfully, cunningly." "You show great cunning or art, in laying aside God's commands and substituting in their place those of men." Others suppose them to be ironical. "How nobly you act! From conscientious attachment to your traditions you have made void the law of God;" meaning to intimate by it that they had acted wickedly and basely.

Full well - Καλως, - a strong irony. How noble is your conduct! From conscientious attachment to your own traditions ye have annihilated the commandments of God!

That ye may keep - But στησητε, that ye may establish, is the reading of D, three others, Syriac, all the Itala, with Cyprian, Jerome, and Zeno. Griesbach thinks it should be received instead of the other. God's law was nothing to these men, in comparison of their own: hear a case in point. "Rabba said, How foolish are most men! They observe the precepts of the Divine law, and neglect the statutes of the rabbins!" Maccoth, fol. 22.

And he said unto them,.... He continued his discourse, saying,

full well, or "fairly",

ye reject the commandment of God, that ye may keep your own tradition: these words may be considered, as spoken ironically, thus; as pious and excellently good men, you in a very fair and handsome manner, reject and make void the commandments and laws of God; and it is very fit it should be so, in order to preserve your own traditions, that nothing may be wanting to keep up the honour of them, and a due regard to them. The Arabic version reads the words by way of interrogation, "is it fit that you should omit the commandments of God, and keep your own statutes?" and so the Ethiopic, "do ye rightly make void the commandment of God, that ye may keep your own commandment?" Which makes them come nearer to the passage in Matthew; See Gill on Matthew 15:3.

{5} And he said unto them, Full well ye reject the commandment of God, that ye may keep your own tradition.

(5) True religion, which is completely contrary to superstition, consists in spiritual worship: and all enemies of true religion, although they seem to have taken deep root, will be plucked up.

reject: or, frustrate

7:1-13 One great design of Christ's coming was, to set aside the ceremonial law; and to make way for this, he rejects the ceremonies men added to the law of God's making. Those clean hands and that pure heart which Christ bestows on his disciples, and requires of them, are very different from the outward and superstitious forms of Pharisees of every age. Jesus reproves them for rejecting the commandment of God. It is clear that it is the duty of children, if their parents are poor, to relieve them as far as they are able; and if children deserve to die that curse their parents, much more those that starve them. But if a man conformed to the traditions of the Pharisees, they found a device to free him from the claim of this duty.
