The words that people speak come from their thoughts. It is what comes out of their mouths that makes them dirty. Bad thoughts come from people’s minds. As a result, they do wrong things. They might decide to kill somebody. They might have sex with another man’s wife or in other wrong ways. They might rob somebody. They might tell lies about other people. Or they might say bad things against them. It is these bad things that make people dirty in front of God. But if people eat food when they have not washed their hands in the right way, that will not make them dirty.’ Matthew 15:18-20
惟獨出口的，是從心裏發出來的，這才污穢人。 因為從心裏發出來的，有惡念、凶殺、姦淫、苟合、偷盜、妄證、謗讟。 這都是污穢人的；至於不洗手吃飯，那卻不污穢人。」 馬太福音 15:18-20
