Matthew 15:18-20

18The words that people speak come from their thoughts. It is what comes out of their mouths that makes them unclean.

19Evil thoughts come out from people's minds. As a result, they do wrong things. They murder people. They have sex with another man's wife. They have sex in other wrong ways. They rob people. They tell lies about other people. They insult people.

20It is these bad things that make people unclean. But if people eat food when they have not washed their hands in the right way, that will not make them unclean.’
