Matt. 15:17 "Do you not understand that whatever goes into the mouth passes into the stomach, then passed into the drain?
18 But whatever comes out of the mouth comes from the heart, and this is what makes a man unclean.
19 For out of the heart come evil thoughts such as murder, adultery, sexual vice, theft, false witnessing, slander, and irreverent speech.
20 These are what make a man unclean and defiled; but eating with unwashed hands does not make him unclean or defiled."
