Mattityahu 15:18

18 But the things coming out from the mouth come out from the lev (heart), which makes tameh.

Mattityahu 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.

Mattityahu 15:18 In-Context

16 And Rebbe, Melech HaMoshiach said, Are you still devoid of binah (understanding)?

17 Do you not have daas that everything which enters into the mouth goes into the stomach and passes into a latrine?

18 But the things coming out from the mouth come out from the lev (heart), which makes tameh.

19 For out of the lev comes evil machshavot (thoughts): retzichot (murders), niufim (adulteries), zenunim (fornications), genevot (thefts), eduyot sheker (false testimonies), giddufim (revilements).

20 These are the things making the man tameh, but eating with hands lacking the netilat yadayim (ritual of the washing of the hands, see Mt 27:24), this does not make the man tameh.
