Matthew 15:4

And since this had no shade of contrariety to the law, to command men to wash their hands, He brings forward another tradition, which is opposed to the law. And what He saith is like this. "They taught the young, under the garb of piety, to despise their fathers." How, and in what way? "If one of their parents said to his child, Give me this sheep that thou hast, or this calf, or any such thing, they used to say, 'This is a gift to God, whereby thou wouldest be profited by me, and thou canst not have it.' And two evils hence arose: on the one hand they did not bring them to God, on the other they defrauded their parents under the name of the offering, alike insulting their parents for God's sake, and God for their parents' sake." But He, omitting the first, the reward appointed for them that honor their parents, states that which is more awful, the punishment, I mean, threatened to such as dishonor them; desiring both to dismay them, and to conciliate such as have understanding; and He implies them to be for this worthy of death. For if he who dishonors them in word is punished, much more ye, who do so in deed, and who not only dishonor, but also teach it to others. "Ye then who ought not so much as to live, how find ye fault with the disciples?" "And what wonder is it, if ye offer such insults to me, who am as yet unknown, when even to the Father ye are found doing the like?" For everywhere He both asserts and implies, that from Him they began with this their arrogance. But some do also otherwise interpret, "It is a gift, by whatsoever thou mightest be profited by me;" that is, I owe thee no honor, but it is a free gift from me to thee, if indeed I do honor thee. But Christ would not have mentioned an insult of that sort. And Mark again makes this plainer, by saying, "It is Corban, by whatsoever thou mightest be profiled by me;" which means, not a gift and present, but properly an offering.

For God hath said, Honour thy father and thy mother. Honour in the Scriptures is shown not so much in salutations and courtesies as in alms and gifts. Honour, (1 Tim. 5:3.) says the Apostle, the widows who are widows indeed; here 'honour' signifies a gift. The Lord then having thought for the infirmity, the age, or the poverty of parents, commanded that sons should honour their parents in providing them with necessaries of life.
