Matthew 15:10-20

He called the crowds and said to them, “Hear and understand: That which goes into the mouth does not defile a man, but that which comes out of the mouth, this defiles a man.” Then His disciples came and said to Him, “Do You know that the Pharisees were offended after they heard this saying?” But He answered, “Every plant which My heavenly Father has not planted will be uprooted. Leave them alone. They are blind leaders of the blind. And if the blind lead the blind, both will fall into the ditch.” Then Peter said to Him, “Explain this parable to us.” Jesus said, “Are you also still without understanding? Do you not yet understand that whatever enters at the mouth goes into the stomach and is cast out into the sewer? But those things which proceed out of the mouth come from the heart, and they defile the man. For out of the heart proceed evil thoughts, murders, adulteries, sexual immorality, thefts, false witness, and blasphemies. These are the things which defile a man. But to eat with unwashed hands does not defile a man.”
