Matthew 15:18

18 but the things which go forth out of the mouth come out of the heart, and those defile man.

Matthew 15:18 Meaning and Commentary

Matthew 15:18

But those things which proceed out of the mouth
Meaning not material things, as spittle, vomit 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.

Matthew 15:18 In-Context

16 But he said, Are *ye* also still without intelligence?

17 Do ye not yet apprehend, that everything that enters into the mouth finds its way into the belly, and is cast forth into the draught?

18 but the things which go forth out of the mouth come out of the heart, and those defile man.

19 For out of the heart come forth evil thoughts, murders, adulteries, fornications, thefts, false witnessings, blasphemies;

20 these are the things which defile man; but the eating with unwashen hands does not defile man.
