Mark 7:2-5

2And they saw that some of Jesus’ disciples ate their bread with unclean hands, that is, unwashed.

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.

4And 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.)

5The 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?”
