Matthew 15:17-20

17Do you not yet understand that whatever enters the mouth goes into the stomach and is eliminated?

18But those things which proceed out of the mouth come from the heart, and they defile a man.

19For out of the heart proceed evil thoughts, murders, adulteries, fornications, thefts, false witness, blasphemies.

20These are the things which defile a man, but to eat with unwashed hands does not defile a man.”
