And he called all the people unto him, and said unto them, "Hearken unto me every one of you and understand: There is nothing without a man that can defile him when it entereth into him, but those things which proceed out of him are those which defile the man.

And when he came into a house away from the people, his disciples asked him of the similitude, and he said unto them, "Are ye so without understanding? Do ye not yet perceive, that whatsoever thing from without entereth into a man, it cannot defile him, because it entereth not into his heart, but into the belly: and goeth out into the draught that purgeth out all meats." And he said, "That defileth a man which cometh out of a man. For from within even out of the heart of men, proceed evil thoughts: adultery, fornication, murder, theft, covetousness, wickedness, deceit, uncleanness, and a wicked eye, blasphemy, pride, foolishness: All these evil things come from within, and defile a man."
