Matthew 15:1-2, 10-11, 15-20 ESV
Then Pharisees and scribes came to Jesus from Jerusalem and said, “Why do your disciples break the tradition of the elders? For they do not wash their hands when they eat.” And he called the people to him and said to them, “Hear and understand: it is not what goes into the mouth that defiles a person, but what comes out of the mouth; this defiles a person.” But Peter said to him, “Explain the parable to us.” And he said, “Are you also still without understanding? Do you not see that whatever goes into the mouth passes into the stomach and is expelled? But what comes out of the mouth proceeds from the heart, and this defiles a person. For out of the heart come evil thoughts, murder, adultery, sexual immorality, theft, false witness, slander. These are what defile a person. But to eat with unwashed hands does not defile anyone.”
