Mark 7:2-4

2 They saw that some of his disciples were unclean because they ate without washing their hands.

3 (The Pharisees, like all other Jewish people, don't eat unless they have properly washed their hands. They follow the traditions of their ancestors.

4 When they come from the marketplace, they don't eat unless they have washed first. They have been taught to follow many other rules. For example, they must also wash their cups, jars, brass pots, and dinner tables. )
