16"Are you still so dull?" Jesus asked them. 17"Don't you see that whatever enters the mouth goes into the stomach and then out of the body? 18But the things that come out of the mouth come from the heart, and these make a man 'unclean.' 19For out of the heart come evil thoughts, murder, adultery, sexual immorality, theft, false testimony, slander. 20These are what make a man 'unclean'; but eating with unwashed hands does not make him 'unclean.'
