Note, 1. The punishment of scorners will be a means of good to others. When men are so hardened in wickedness that they will not themselves be wrought upon by the severe methods that are used to reclaim and reform them, yet such methods must be used for the sake of others, that they may hear and fear, Deu 19:20. If the scorner will not be recovered from his sin, the disease being inveterate, yet the simple will beware of venturing upon the sin which exposes men thus. If it cure not the infected, it may prevent the spreading of the infection. 2. The reproof of wise men will be a means of good to themselves. They need not be smitten; a word to the wise is enough. Do but reprove one that has understanding and he will so far understand himself and his own interest that he will understand knowledge by it, and not miss it again through ignorance and inadvertency when once he has been told of it; so kindly does he take reproof and so wisely improve it.

Smite a scorner, and the simple will beware,.... That is, give reproof to a man that scoffs at religion, and makes a jest of all that is good; for though it may be of no use to him who will despise it, yet it may be observed, and be useful to another that hears it; who, though void of understanding, yet not hardened in impiety as the other, but open to conviction, "will become cunning" (x), as it may be rendered; or learns wisdom, and becomes hereby a knowing and understanding man; he hears another reproved, and fears, and becomes a wise man; so that though reproof may be lost on one, it succeeds in another, which is an encouragement to give it;

and reprove one that hath understanding, and he will understand knowledge; he will grow wiser and wiser; he will improve in the knowledge of things; see Pro 9:8.

(x) "astutus efficetur", Pagninus, Montanus; "astutus fiet", Junius & Tremellius, Cocceius; "astutior fiet", Michaelis; "solertiam parabit", Schultens.

Such is the benefit of reproof; even the simple profit, much more the wise.
