Mark 7:20-23; Matthew 15:11

20 And He said, "What comes out of a man, that defiles a man. 21 For from within, out of the heart of men, proceed evil thoughts, adulteries, fornications, murders, 22 thefts, covetousness, wickedness, deceit, lewdness, an evil eye, blasphemy, pride, foolishness. 23 All these evil things come from within and defile a man."
11 Not what goes into the mouth defiles a man; but what comes out of the mouth, this defiles a man."
