'Defile' in the Bible

There is nothing from without a man, that entering into him can defile him: but the things which come out of him, those are they that defile the man.

And he saith unto them, Are ye so without understanding also? Do ye not perceive, that whatsoever thing from without entereth into the man, it cannot defile him;

All these evil things come from within, and defile the man.
