Matthew 15:15-20

15But Peter said to him, “Explain the parable to us.” 16And he said, “Are you also still without understanding? 17Do you not see that whatever goes into the mouth passes into the stomach and is expelled? 18But what comes out of the mouth proceeds from the heart, and this defiles a person. 19For out of the heart come evil thoughts, murder, adultery, sexual immorality, theft, false witness, slander. 20These are what defile a person. But to eat with unwashed hands does not defile anyone.”
