It is as sport to a fool to do mischief: but a man of understanding hath wisdom.

Jamieson-Fausset-Brown Bible Commentary

23. Sin is the pleasure of the wicked; wisdom that of the good.

Matthew Henry's Concise Commentary

10:22. That wealth which is truly desirable, has no vexation of spirit in the enjoyment; no grief for the loss; no guilt by the abuse of it. What comes from the love of God, has the grace of God for its companion. 23. Only foolish and wicked men divert themselves with doing harm to others, or tempting to sin. 24. The largest desire of eternal blessings the righteous can form, will be granted. 25. The course of prosperous sinners is like a whirlwind, which soon spends itself, and is gone. 26. As vinegar sets the teeth on edge, and as the smoke causes the eyes to smart, so the sluggard vexes his employer. 27,28. What man is he that loves life? Let him fear God, and that will secure to him life enough in this world, and eternal life in the other.

Matthew Henry's Whole Bible Commentary

Verse 23

Here is, 1. Sin exceedingly sinful: It is as laughter to a fool to do mischief; it is as natural to him, and as pleasant, as it is to a man to laugh. Wickedness is his Isaac (that is the word here); it is his delight, his darling, and that in which he pleases himself. He makes a laughing matter of sin. When he is warned not to sin, from the consideration of the law of God and the revelation of his wrath against sin, he makes a jest of the admonition, and laughs at the shaking of the spear; when he has sinned, instead of sorrowing for it, he boasts of it, ridicules reproofs, and laughs away the convictions of his own conscience, ch. 14:9. 2. Wisdom exceedingly wise, for it carries along with it the evidence of its own excellency; it may be predicated of itself, and this is encomium enough; you need say no more in praise of a man of understanding than this, "He is an understanding man; he has wisdom; he is so wise as not to do mischief, or if he has, through oversight, offended, he is so wise as not to make a jest of it." Or, to pronounce wisdom wise indeed, read it thus: As it is a sport to a fool to do mischief, so it is to a man of understanding to have wisdom and to show it. Besides the future recompence, a good man has as much present pleasure in the restraints and exercises of religion as sinners can pretend to in the liberties and enjoyments of sin, and much more, and much better.
