'Defile' in the Bible

there is nothing from without the man entering into him that is able to defile him, but the things coming out from him, those are the things defiling the man.

and he saith to them, 'So also ye are without understanding! Do ye not perceive that nothing from without entering into the man is able to defile him?

And he said -- 'That which is coming out from the man, that doth defile the man;

all these evils do come forth from within, and they defile the man.'
