Matthew 15:4-6
4. For God commanded, saying, Honour thy father and mother— (De 5:16).
and, He that curseth father or mother, let him die the death— (Ex 21:17).5. But ye say, Whosoever shall say to his father or his mother, It is a gift—or simply, "A gift!" In Mark (Mr 7:11), it is, "Corban!" that is, "An oblation!" meaning, any unbloody offering or gift dedicated to sacred uses.
by whatsoever thou mightest be profited by me;6. And honour not his father or his mother, he shall be free —that is, It is true, father—mother—that by giving to thee this, which I now present, thou mightest be profited by me; but I have gifted it to pious uses, and therefore, at whatever cost to thee, I am not now at liberty to alienate any portion of it. "And," it is added in Mark (Mr 7:12), "ye suffer him no more to do aught for his father or his mother." To dedicate property to God is indeed lawful and laudable, but not at the expense of filial duty.
Thus have ye made the commandment of God of none effect—cancelled or nullified it "by your tradition."
