(6) Well hath Esaias prophesied.--Strictly, well did Esaias prophesy.

Verses 6, 7. - Our Lord quotes against them a prophecy of Isaiah (Isaiah 29:13), This people honoureth me with their lips, but their heart is far from me. But in vain do they worship me, teaching as their doctrines the precepts of men. The prophet here gives the cause of the blindness of the Jews, because they honored God with their lips, while their heart was far from him; and their worship of him (for that is the meaning of "their fear") was the commandment of men, which they had been taught; that is, they worshipped God, not according to that spiritual worship which he had commanded, but after the traditions of men and of their own scribes, partly futile, partly perverse, and contrary to God's Law. So he says, Well did Isaiah prophesy of you. The word is καλῶς, "excellently - beautifully - did he prophesy concerning you (τῶν ὑποκριτῶν), the hypocrites." Not that the prophet had the hypocrites of our Saviour's time in his mind when he uttered these words, but that the Spirit of God which was within him enabled him to describe accurately the character of those who seven centuries afterwards would be doing the same things as their forefathers. And observe how they were punished. For as they gave a lip-service only to God, praising him with their mouth indeed, but giving their heart to vanity and the world; so God on his part would give them the words only - the shell, so to speak, the letter which killeth; but take away from them the kernel the spirit and the life, so that they might not lay hold of it nor taste it.

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.He answered and said unto them,.... Matthew postpones the following citation and application of the prophecy of Isaiah, to the account of the command of God being broken by the tradition of Corban; which Mark makes the answer of Christ to begin with:

well hath Esaias prophesied of you hypocrites; which in Matthew is read, "ye hypocrites, well did Esaias prophesy of you", Matthew 15:7; to the same sense as here: for the prophecy of Isaiah not only described the hypocrites of his time, but had respect chiefly to the Jews in succeeding ages, in the times of Christ, and both before and after; when they would, as they did, greatly degenerate, and lost the power and spirituality of religion, and had only the form of it; left the word of God for the traditions of men, and were given up to great stupidity, and to judicial blindness: hence the Apostle Paul refers to a passage in the same chapter, Isaiah 29:10, and applies it to the Jews in his time, Romans 11:8; See Gill on Matthew 15:7, saying,

as it is written in Isaiah 29:13,

this people honoureth me with their lips, but their heart is far from me. In the Prophet Isaiah more is said than is here cited; and so in Matthew more is produced, and the whole is there expressed thus: "this people draweth nigh unto me with their mouth, and honoureth me with their lips, but their heart is far from me", Matthew 15:8, they presented their bodies before the Lord in the synagogues, or in the temple, and prayed to him with an air of devotion and fervency, and offered up their praises to him, for their external privileges and blessings; but, alas! this was all lip labour; there was no lifting up their hearts, with their hands, unto God; these were not united to fear his name, but were distracted in his worship, and carried away from him to other objects; See Gill on Matthew 15:8.
