Matthew 15:16-20

16 Jesus replied, ‘I am surprised that you still do not understand what I am saying. 17 You should understand that food first goes into people's mouths. Then it goes into their stomach, and then it passes out of their body. 18 The words that people speak come from their thoughts. It is what comes out of their mouths that makes them unclean. 19  Evil thoughts come 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.

20 It 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.’
