Matthew 15:17-20

17“Do you not yet realize that whatever enters the mouth goes into the stomach and then is eliminated? 18But the things that come out of the mouth come from the heart, and these things defile a man. 19For out of the heart come evil thoughts, murder, adultery, sexual immorality, theft, false testimony, and slander. 20These are what defile a man, but eating with unwashed hands does not defile him.”
