25 Smite a scorner, and the simple will beware: and reprove one that hath understanding, and he will understand knowledge.
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,Deuteronomy 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.
