Matthew 15:17-20
15:17 Don’t you understand that whatever goes into the mouth enters the stomach and then passes out into the sewer?
15:18 But the things that come out of the mouth come from the heart, and these things defile a person.
15:19 For out of the heart come evil ideas, murder, adultery, sexual immorality, theft, false testimony, slander.
15:20 These are the things that defile a person; it is not eating with unwashed hands that defiles a person.”
