Mark 7:1-4

The Pharisees and some of the scribes gathered around Him when they had come from Jerusalem, and had seen that some of His disciples were eating their bread with impure hands, that is, unwashed. (For the Pharisees and all the Jews do not eat unless they carefully wash their hands, thus observing the traditions of the elders; and when they come from the market place, they do not eat unless they cleanse themselves; and there are many other things which they have received in order to observe, such as the washing of cups and pitchers and copper pots.)
