What is the meaning of Matthew 15:3-6?

3 But he answered and said unto them, Why do ye also transgress the commandment of God by your tradition? 4 For God commanded, saying, Honour thy father and mother: and, He that curseth father or mother, let him die the death. 5 But ye say, Whosoever shall say to his father or his mother, It is a gift, by whatsoever thou mightest be profited by me; 6 And honour not his father or his mother, he shall be free. Thus have ye made the commandment of God of none effect by your tradition. (Matthew 15:3-6 KJV)

William Burkitt’s Commentary

Observe here, 1. The heavy charge which our Saviour brings in against the Pharisees; namely, for violating an express command of God, and preferring their own traditions before it: you make void the commandments of God by your traditions.

Observe, 2. The command which our Saviour instances in, as violated by them; it is the fifth commandment, which requires children to relieve their parents in necessity. Now, though the Pharisees did not deny this in plain terms, yet they made an exception from it, which if children had a mind, rendered it void and useless. For the Pharisees taught, that in case any would give a gift to the temple, which gift they called corban, and of which they themselves had a great share; that then children were discharged from making further provision for their poor, or impotent parents; and might say unto them after this manner, that which thou askest for thy supply, is given to God, and therefore I cannot relieve thee. So that covetous and graceless children looked upon it as the most frugal way, once for all to fine to the temple, rather than pay the constant rent of daily relief to their poor parents.

Learn, that no duty, gift, or offering to God, is accepted, where the duty of charity is neglected. It is more acceptable to God to refresh the hearts of his saints, who are the living temples of the Holy Ghost, than to adorn material temples with gold and silver.
