'Tradition' in the Bible

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

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?

For laying aside the commandment of God, ye hold the tradition of men, as the washing of pots and cups: and many other such like things ye do.

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

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