Matthew 15 is appropriate here
"
1Then came to Jesus scribes and Pharisees, which were of Jerusalem, saying,
2Why do thy disciples transgress the tradition of the elders? for they wash not their hands when they eat bread.
3But he answered and said unto them,
Why do ye also transgress the commandment of God by your tradition? 4For God commanded, saying, Honour thy father and mother: and, He that curseth father or mother, let him die the death.
5But ye say, Whosoever shall say to
his father or
his mother,
It is a gift, by whatsoever thou mightest be profited by me;
6And 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.
7Ye hypocrites, well did Esaias prophesy of you, saying,
8This people draweth nigh unto me with their mouth, and honoureth me with their lips; but their heart is far from me.
9But in vain they do worship me, teaching for doctrines the commandments of men."
