Matthew 15:11

Not that which goeth into the mouth defileth a man; but that which cometh out of the mouth, this defileth a man.

Publicly had He been attacked by the Pharisees, publicly He defended Himself. There is a definite connection of this parabolic saying with the matter in dispute. This they should note carefully and try to understand. His reference is to moral defilement, to uncleanness of the soul. His distinction is that physical cleanness or uncleanness does not affect the heart, but that moral pollution will stain both heart and character. "This fine and pleasing contrast, 'going in' and 'coming out. ' is attractive. As though He would say: Why, what do they bother themselves with eating and drinking, or with that which enters into the mouth? Let them rather pay attention to that which goes out of the mouth. This we ought to watch. What goes into the mouth, that does not defile; but what goes out of the mouth, that defiles. Oh, those are detestable hypocrites, that are careful not to be defiled by those things that go into the mouth (which are God's creature); why do they not rather watch this which comes out of the mouth, which are works of the devil?"
