Matthew 15:17-20

17Don’t you understand that whatever goes into the mouth enters the stomach and then passes out into the sewer?

18But the things that come out of the mouth come from the heart, and these things defile a person.

19For out of the heart come evil ideas, murder, adultery, sexual immorality, theft, false testimony, slander.

20These are the things that defile a person; it is not eating with unwashed hands that defiles a person.”
