Understanding is a wellspring of life to him that hath it: but the {l} instruction of fools is folly.

(l) Either that which the wicked teach others, or else it is folly to teach them who are malicious.

Wesley's Notes

16:22 The instruction - Their most grave and serious counsels are foolish.

Jamieson-Fausset-Brown Bible Commentary

22. Understanding-or, "discretion," is a constant source of blessing (Pr 13:14), benefiting others; but fools' best efforts are folly.

Matthew Henry's Concise Commentary

16:12. The ruler that uses his power aright, will find that to be his best security. 13. Put those in power who know how to speak to the purpose. 14,15. Those are fools, who, to obtain the favour of an earthly prince, throw themselves out of God's favour. 16. There is joy and satisfaction of spirit, only in getting wisdom. 17. A sincerely religious man keeps at a distance from every appearance of evil. Happy is the man that walks in Christ, and is led by the Spirit of Christ. 18. When men defy God's judgments, and think themselves far from them, it is a sign they are at the door. Let us not fear the pride of others, but fear pride in ourselves. 19. Humility, though it exposes to contempt in the world, is much better than high-spiritedness, which makes God an enemy. He that understands God's word shall find good. 21. The man whose wisdom dwells in his heart, will be found more truly prudent than many who possess shining talents. 22. As waters to a thirsty land, so is a wise man to his friends and neighbours. 23. The wise man's self-knowledge, always suggests something proper to be spoken to others. 24. The word of God cures the diseases that weaken our souls. 25. This is caution to all, to take heed of deceiving themselves as to their souls. 26. We must labour for the meat which endureth to everlasting life, or we must perish.

Matthew Henry's Whole Bible Commentary

Verse 22

Note, 1. There is always some good to be gotten by a wise and good man: His understanding is a well-spring of life to him, which always flows and can never be drawn dry; he has something to say upon all occasions that is instructive, and of use to those that will make use of it, things new and old to bring out of his treasure; at least, his understanding is a spring of life to himself, yielding him abundant satisfaction; within his own thoughts he entertains and edifies himself, if not others. 2. There is nothing that is good to be gotten by a fool. Even his instruction, his set and solemn discourses, are but folly, like himself, and tending to make others like him. When he does his best it is but folly, in comparison even with the common talk of a wise man, who speaks better at table than a fool in Moses's seat.
