'Washing' in the Bible

and they had seen that some of His disciples ate their bread with [ceremonially] impure hands, that is, unwashed [and defiled according to Jewish religious ritual].

and when they come from the market place, they do not eat unless they cleanse themselves [completely according to ritual]; and there are many other things [oral, man-made laws and traditions handed down to them] which they follow diligently, such as the washing of cups and pitchers and copper utensils.)
