Mark 7:1-8

The Pharisees and religious leaders who had come down from Jerusalem to meet Jesus noticed that some of his disciples ate with “unclean” (meaning unwashed) hands. (The Pharisees and all Jews don't eat until they wash their hands, following the tradition of their ancestors. In the same way, they don't eat when they return from the market until they have had a wash. They observe many other rituals, like the washing of cups, pots, and pans.) So the Pharisees and religious leaders asked Jesus, “Why don't your disciples follow the tradition of our ancestors? They eat food with unclean hands.” Jesus replied, “Isaiah was right about you hypocrites when he said, ‘These people claim they honor me, but in their thinking they are far from me. There's no point in their worship of me, for what they teach as doctrines are merely human rules.’ You disregard God's law, and instead you carefully observe human traditions.”
