Verse 13. - Wisdom is found (comp. Psalm 37:30). The man of understanding is discreet in speech, and does not cause trouble by rash or foolish words. A rod (Proverbs 19:29; Proverbs 26:3). A fool brings upon himself punishment by his insensate talk. Void of understanding; Hebrew, "wanting in heart;" Vulgate, qui indiget corde. The LXX. combines the two members into one proposition, "He who putteth forth wisdom with his lips is a rod to chastise the man without heart." In the Hebrew conception the "heart" is the seat, not only of the passions and affections, but also of the intellectual faculties.

10:7. Both the just and the wicked must die; but between their souls there is a vast difference. 8. The wise in heart puts his knowledge in practice. 9. Dissemblers, after all their shuffling, will be exposed. 10. Trick and artifice will be no excuse for iniquity. 11. The good man's mouth is always open to teach, comfort, and correct others. 12. Where there is hatred, every thing stirs up strife. By bearing with each other, peace and harmony are preserved. 13. Those that foolishly go on in wicked ways, prepare rods for themselves. 14. Whatever knowledge may be useful, we must lay it up, that it may not be to seek when we want it. The wise gain this wisdom by reading, by hearing the word, by meditation, by prayer, by faith in Christ, who is made of God unto us wisdom. 15. This refers to the common mistakes both of rich and poor, as to their outward condition. Rich people's wealth exposes them to many dangers; while a poor man may live comfortably, if he is content, keeps a good conscience, and lives by faith. 16. Perhaps a righteous man has no more than what he works hard for, but that labour tends to life. 17. The traveller that has missed his way, and cannot bear to be told of it, and to be shown the right way, must err still. 18. He is especially a fool who thinks to hide anything from God; and malice is no better. 19. Those that speak much, speak much amiss. He that checks himself is a wise man, and therein consults his own peace. 20,21. The tongue of the just is sincere, freed from the dross of guile and evil design. Pious discourse is spiritual food to the needy. Fools die for want of a heart, so the word is; for want of thought.In the lips of him that hath understanding wisdom is found,.... He that has an understanding, especially of divine, spiritual, and evangelic things, which is the pure gift of God; wisdom will be found in his lips, his mouth will speak of it; not of mere natural wisdom, but spiritual wisdom; of the wisdom of God in his works; of Christ, the Wisdom of God; of the Gospel, the hidden wisdom; of inward experience of the grace of God, wisdom in the inward part, Psalm 37:30; from his lips will drop wise sayings, very instructive and informing; which those that seek for and observe may find to their profit and advantage, and to the great credit and honour of the understanding man; while the foolish man gets both stripes and disgrace, as follows;

but a rod is for the back of him that is void of understanding; or, "wants a heart" (e): that has no understanding of spiritual things in his heart, and so utters nothing but what is foolish and wicked, and, sooner or later, is chastised for it. The Septuagint, Syriac, and Arabic versions, read this clause in connection with the former, thus; "he that brings forth wisdom out of his lips smites with a rod him that is void of understanding".

(e) "carcutis corde"; Montanus, Mercerus, Gejerus.
