(14) The mouth of the foolish is near destruction—i.e., is a near, ever-threatening calamity; one never knows what awkward or dangerous thing he will not say next: whereas wise men store up knowledge, and bring it forth as it is wanted (Matthew 13:52).

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.Lay up - The point of the maxim is that the wise man reserves what he has to say for the right time, place, and persons (compare Matthew 7:6), as contrasted with the foolish, ever giving immediate utterance to what destroys himself and others. 14. lay up knowledge—that is, as treasures for good use.

mouth … destruction—or, "as to the mouth," &c., destruction is near; they expose themselves to evil by prating.

Wise men lay up, to wit, in their minds and memories, to be brought forth thence upon fit occasions,

knowledge; whereby they may be enabled to speak both what and when it is seasonable, for their own or others’ good.

The mouth of the foolish is near destruction; fools are more forward to lay out than to lay up, and for want of knowledge speak much and foolishly, whereby they frequently bring destruction upon themselves

Wise men lay up knowledge,.... Which they get by reading, prayer, meditation, hearing the word of God, and conversation with good men: this they lay up in their hearts, minds, and memories, that they may not forget it, and as a rich treasure they highly value it; that they may bring it forth at proper times, and on proper occasions, for the benefit of others; see Matthew 12:35; or hide (f) it; conceal it; do not boast and brag of it, as foolish men do;

but the mouth of the foolish is near destruction: who rashly and unguardedly utters things which bring swift and sudden destruction on himself and others; or terror and consternation, as the word (g) also signifies. The Vulgate Latin version is, "but the mouth of the foolish is near to confusion"; he boasts of his knowledge, betrays his ignorance, and so brings himself to shame and confusion.
