Proverbs 26:5

5 Answer the fool according to his folly, Lest he regard himself as wise. ענה־כסיל (with Makkeph, and Gaja, and Chatef) (Note: Thus after Ben Asher; while, on the contrary, Ben Naphtali writes ענה כסיל with Munach, vid., Thorath Emeth, p. 41.) here stands opposed to אל־תען כסיל. The Gospel of John, e.g., Joh 5:31, cf. Pro 8:31, (Note: Vid., my dissertation on three little-observed passages in the Gospel of John, and their practical lessons, in the Evang. luth. Kirchenzeitung, 1869, Nos. 37, 38.) is rich in such apparently contradictory sayings. The sic et non here lying before us is easily explained; after, or according to his folly, is this second time equivalent to, as is due to his folly: decidedly and firmly rejecting it, making short work with it (returning a sharp answer), and promptly replying in a way fitted, if possible, to make him ashamed. Thus one helps him, perhaps, to self-knowledge; while, in the contrary case, one gives assistance to his self-importance. The Talmud, Schabbath 30b, solves the contradiction by referring Pro 26:4 to worldly things, and Pro 26:5 to religious things; and it is true that, especially in the latter case, the answer is itself a duty toward the fool, and towards the truth. Otherwise the Midrash: one ought not to answer when one knows the fool as such, and to answer when he does not so know him; for in the first instance the wise man would dishonour himself by the answer, in the latter case he would give to him who asks the importance appertaining to a superior.

Note, 1. It is too common a thing for honour to be given to fools, who are utterly unworthy of it and unfit for it. Bad men, who have neither wit nor grace, are sometimes preferred by princes, and applauded and cried up by the people. Folly is set in great dignity, as Solomon observed, Ecc 10:6. 2. It is very absurd and unbecoming when it is so. It is an incongruous as snow in summer, and as great a disorder in the commonwealth as that is in the course of nature and in the seasons of the year; nay, it is as injurious as rain in harvest, which hinders the labourers and spoils the fruits of the earth when they are ready to be gathered. When bad men are in power they commonly abuse their power, in discouraging virtue, and giving countenance to wickedness, for want of wisdom to discern it and grace to detest it.
