馬太福音(Matthew)15:16-18

耶穌說：你們到如今還不明白嗎？ 豈不知凡入口的，是運到肚子裡，又落在茅廁裡嗎？ 惟獨出口的，是從心裡發出來的，這纔污穢人。
Are you still so dull? Jesus asked them. Dont you see that whatever enters the mouth goes into the stomach and then out of the body? But the things that come out of a persons mouth come from the heart, and these defile them.
