'Traditions' in the Bible

(For the Pharisees and all the Jews do not eat unless they wash their hands {ritually}, [thus] holding fast to the traditions of the elders.

And [when they come] from the marketplace, they do not eat unless they wash. And there are many other [traditions] which they have received [and] hold fast to--[for example,] the washing of cups and pitchers and bronze kettles and dining couches.)
