Matthew 15:18

18 But the things which proceed out of the mouth come forth out of the heart, and they defile the 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 So Jesus said, "Do you also still not understand?

17 Don't you understand that whatever goes into the mouth passes into the belly, and then out of the body?

18 But the things which proceed out of the mouth come forth out of the heart, and they defile the man.

19 For out of the heart come forth evil thoughts, murders, adulteries, sexual sins, thefts, false testimony, and blasphemies.

20 These are the things which defile the man; but to eat with unwashed hands doesn't defile the man."
