But the things which proceed out of the mouth, come forth from the heart, and those things defile a man.

but the things coming forth from the mouth from the heart do come forth, and these defile the man;

But the things that come out of the mouth proceed from the heart, and it is these that defile the man.

But the things which come out of the mouth come from the heart; and they make a man unclean.

But what proceeds from the mouth, goes forth from the heart, and those are the things that defile a man.

But the things that come out of the mouth proceed from the heart, and it is these that defile a person;

But those things which proceed out of the mouth,.... Meaning not material things, as spittle, vomit, &c. but, as it follows, which
come forth from the heart: are first conceived and formed there, and then come forth from thence, and are expressed by the mouth; as all idle words, foolish talking, filthy jesting, unsavoury communication, and every word that is rotten and corrupt, or which is done in the life and conversation;
and they defile the man: the heart is the corrupt fountain from whence all moral defilement flows; and sinful words and actions are the impure streams, which spring from thence, and increase the moral pollution of human nature.

Out of the heart. The emotional nature; the mind. Evil deeds are begotten of evil thoughts; evil words are the expression of these evil thoughts. These indicate a sinful heart and make a man sinful, or defiled.
