21:11 When a scorner is punished, the naive 1 becomes wise;
when a wise person is instructed, 2 he gains knowledge.
1 sn The contrast here is between the simple and the wise. The simple gain wisdom when they see the scorner punished; the wise gains knowledge through instruction. The scorner does not change, but should be punished for the benefit of the simple (e.g., Prov 19:25).
2 tn Heb “in the instructing of the wise.” The construction uses the Hiphil infinitive construct הַשְׂכִּיל (haskil) with a preposition to form a temporal clause (= “when”). The word “wise” (חָכָם, khakham) after it is the subjective genitive. The preposition לְ (lamed) on the form is probably dittography from the ending of the infinitive.
