Matthew 15:17-20

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 a person’s mouth come from the heart, and these defile them.

19For out of the heart come evil thoughts—murder, adultery, sexual immorality, theft, false testimony, slander.

20These are what defile a person; but eating with unwashed hands does not defile them.”
