Mark 7:1-8 The Pharisees and some of the teachers of the law who had come from 
Jerusalem gathered around Jesus and 2 saw some of his disciples eating food with hands that were "unclean," that is, unwashed. 3 (The Pharisees and all the Jews do not eat unless they give their hands a ceremonial washing, holding to the tradition of the elders. 4 When they come from the marketplace they do not eat unless they wash. And they observe many other traditions, such as the washing of cups, pitchers and kettles.) 5 So the Pharisees and teachers of the law asked Jesus, "Why don't your disciples live according to the tradition of the elders instead of eating their food with ‘unclean' hands?" 6 He replied, "Isaiah was right when he prophesied about you hypocrites; as it is written: "‘These people honor me with their lips, but their hearts are far from me. 7 They worship me in vain; their teachings are but rules taught by men.' 8 You have let go of the commands of God and are holding on to the traditions of men."
