Proverbs 18:21

Death and life--or, the greatest evil and good. that love it--that is, the tongue, or its use for good or evil. eat . . . fruit--(Compare Pro 18:19; Jam 1:19).

Death and life are in the power of the tongue,.... Of witnesses, according to the testimony they bear; of judges, according to the sentence they pass; of teachers, according to the doctrine they preach; of all men, who, by their well or ill speaking, bring death or life to themselves and others. Some, by their tongues, by the too free use of them, or falsehood they utter, are the cause of death to themselves and others; and some, by their silence, or by their prudent speech and prevalent intercession, secure or obtain life for themselves and others; yea, judgment at the last day will proceed according to a man's words, "By thy words thou shalt be justified, and by thy words thou shalt be condemned", Mat 12:37; the tongue is the instrument either of a great deal of good, or of a great deal of evil; and they that love it shall eat the fruit thereof; that delight to be talkative; that love to use the tongue, whether in a good or in a bad way, shall accordingly be recompensed; shall enjoy the advantages or disadvantages arising from it.

Note, 1. A man may do a great deal of good, or a great deal of hurt, both to others and to himself, according to the use he makes of his tongue. Many a one has been his own death by a foul tongue, or the death of others by a false tongue; and, on the contrary, many a one has saved his own life, or procured the comfort of it, by a prudent gentle tongue, and saved the lives of others by a seasonable testimony or intercession for them. And, if by our words we must be justified or condemned, death and life are, no doubt, in the power of the tongue. Tongues were Aesop's best meat, and his worst. 2. Men's words will be judged of by the affections with which they speak; he that not only speaks aright (which a bad man may do to save his credit or please his company), but loves to speak so, speaks well of choice, and with delight, to him it will be life; and he that not only speaks amiss (which a good man may do through inadvertency), but loves to speak so (Psa 52:4), to him it will be death. As men love it they shall eat the fruit of it.

18:21 Life and death: The wise speak thoughtfully (10:19; 11:12; 12:23) because they know that what we say has consequences (13:3; 14:3).
