Mark 7:2-5

2and 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].

3(For the Pharisees and all of the Jews do not eat unless they carefully wash their hands, holding firmly to the traditions of the elders;

4and 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.)

5So the Pharisees and scribes asked Jesus, “Why do Your disciples not live their lives according to the tradition of the elders, but [instead] eat their bread with [ceremonially] unwashed hands?”
