Matthew 15:10-20

He called the crowd over and told them, “Listen, and understand this: it's not what goes into you through your mouth that defiles you. It's what comes out of your mouth that defiles you.” Then Jesus' disciples came to him and said, “You do realize that the Pharisees were offended by what you said.” “Every plant my heavenly Father didn't plant will be uprooted,” Jesus replied. “Forget about them—they are blind guides. If a blind man leads another blind man, then they'll both fall into a ditch.” Then Peter asked, “Please tell us what you mean by this illustration.” “Haven't you understood this yet?” replied Jesus. “Don't you see that whatever goes in through the mouth then passes through the stomach, and then leaves the body as waste? But what comes out through the mouth comes from the mind, and that's what defiles you. For what comes from the mind are evil thoughts, murder, adultery, sexual immorality, theft, false witness, and blasphemy and those are what defile you. Eating with unwashed hands doesn't defile you.”
