[12:16] 1 tn Heb “The fool, at once his vexation is known.” This rhetorically emphatic construction uses an independent nominative absolute, which is then followed by the formal subject with a suffix. The construction focuses attention on “the fool,” then states what is to be said about him.
[12:16] 2 tn Heb “on the day” or “the same day.”
[12:16] 4 tn Heb “covers.” The verb כָּסָה (casah) means “covers” in the sense of ignores or bides his time. The point is not that he does not respond at all, but that he is shrewd enough to handle the criticism or insult in the best way – not instinctively and irrationally.
[12:23] 5 tn Heb “a shrewd man” (so NAB); KJV, NIV “a prudent man”; NRSV “One who is clever.”
[12:23] 6 sn The term כֹּסֶה (koseh, “covers; hides”) does not mean that he never shares his knowledge, but discerns when it is and is not appropriate to speak.
[12:23] 7 tn Heb “the heart of fools.” The term לֵב (lev, “heart”) functions as a synecdoche of part (= heart) for the whole (= person): “foolish people.” This type of fool despises correction and instruction. His intent is to proclaim all that he does – which is folly. W. McKane says that the more one speaks, the less likely he is able to speak effectively (Proverbs [OTL], 422). Cf. TEV “stupid people advertise their ignorance”; NLT “fools broadcast their folly.”
[12:23] 8 sn The noun אִוֶּלֶת (’ivvelet, “foolishness; folly”) is the antithesis of perception and understanding. It is related to the noun אֱוִּיל (’evvil, “fool”), one who is morally bad because he despises wisdom and discipline, mocks at guilt, is licentious and quarrelsome, and is almost impossible to rebuke.
