Mark 7:2-5

7:2 And they saw that some of Jesus’ disciples ate their bread with unclean hands, that is, unwashed. 7:3 (For the Pharisees and all the Jews do not eat unless they perform a ritual washing, holding fast to the tradition of the elders. 7:4 And when they come from the marketplace, they do not eat unless they wash. They hold fast to many other traditions: the washing of cups, pots, kettles, and dining couches.) 7:5 The Pharisees and the experts in the law asked him, “Why do your disciples not live according to the tradition of the elders, but eat with unwashed hands?”

Mark 7:8

7:8 Having no regard for the command of God, you hold fast to human tradition.”
