Mark 7:8 (KJV)

For the Pharisees, and all the Jews, except they wash their hands oft, eat not, holding the tradition of the elders.

And when they come from the market, except they wash, they eat not. And many other things there be, which they have received to hold, as the washing of cups, and pots, brasen vessels, and of tables.

Then the Pharisees and scribes asked him, Why walk not thy disciples according to the tradition of the elders, but eat bread with unwashen hands?

He answered and said unto them, Well hath Esaias prophesied of you hypocrites, as it is written, This people honoureth me with their lips, but their heart is far from me.

Howbeit in vain do they worship me, teaching for doctrines the commandments of men.

And he said unto them, Full well ye reject the commandment of God, that ye may keep your own tradition.

For Moses said, Honour thy father and thy mother; and, Whoso curseth father or mother, let him die the death:

But ye say, If a man shall say to his father or mother, It is Corban, that is to say, a gift, by whatsoever thou mightest be profited by me; he shall be free.

And ye suffer him no more to do ought for his father or his mother;

Making the word of God of none effect through your tradition, which ye have delivered: and many such like things do ye.
