This we had before (Pro 19:25), and it shows that there are two ways by which the simple may be made wise: - 1. By the punishments that are inflicted on those that are incorrigibly wicked. Let the law be executed upon a scorner, and even he that is simple will be awakened and alarmed by it, and will discern, more than he did, the evil of sin, and will take warning by it and take heed. 2. By the instructions that are given to those that are wise and willing to be taught: When the wise is instructed by the preaching of the word he (not only the wise himself, but the simple that stands by) receives knowledge. It is no injustice at all to take a good lesson to ourselves which was designed for another.

When the scorner is punished,.... Either by the immediate hand of God, or by the civil magistrate; he who scoffs at Deity, blasphemes the most High, mocks at all religion, despises dominion, and speaks evil of dignities:

the simple is made wise; who is weak and foolish, easily persuaded and drawn into sin, yet not hardened in it, but open to reproof and conviction; he takes notice of the punishment of scorners, and takes warning from it, and behaves more wisely and cautiously for the future; see Pro 19:25;

and when the wise is instructed; by others, superior to him in wisdom; by the ministers of the Gospel, by reading and hearing the word of God, and the writings of good men; or by corrections and chastisements:

he receiveth knowledge; the wise man receives it, he attends to the instruction given him, and improves in knowledge: or rather the simple man gains knowledge by the instructions given to wise men; he learns by them, as well as by what he is taught himself. It is by some rendered, "when the wise prospers, he receiveth knowledge" (x) the simple man learns much both from the adversity and prosperity of others; and to this sense is the note of Gersom,

"when he sees how the ways of a wise man prosper, then he studies to get knowledge.''

(x) So Munster, and some in Mercer.

(Compare Pro 19:25). That which the simple learn by the terrors of punishment, the wise learn by teaching.
