Proverbs 14:33

33 Wisdom rests in the heart of the man of understanding; But the heart of fools it maketh itself known. Most interpreters know not what to make of the second line here. The lxx (and after it the Syr.), and as it appears, also Aquila and Theodotion, insert οὐ; the Targ. improves the Peshito, for it inserts אוּלת (so that Pro 12:23; Pro 13:16, and Pro 15:2 are related). And Abulwald explains: in the heart of fools it is lost; Euchel: it reels about; but these are imaginary interpretations resting on a misunderstanding of the passages, in which ידע means to come to feel, and הודיע to give to feel (to punish, correct). Kimchi rightly adheres to the one ascertained meaning of the words, according to which the Venet. μέσον δὲ ἀφρόνων γνωσθήσεται. So also the translation of Jerome: et indoctos quosque (quoque) erudiet, is formed, for he understands the "and is manifest among fools" (Luther) not merely, as C. B. Michaelis, after the saying: opposita juxta se posita magis elucescunt, but of a becoming manifest, which is salutary to these. Certainly בּקרב can mean among = in the circle, of Pro 15:31; but if, as here and e.g., Jer 31:31, בקרב is interchanged with בלב, and if חכמה בקרב is the subject spoken of, as Kg1 3:28, then בקרב does not mean among (in the midst of), but in the heart of the fool. According to this, the Talmud rightly, by comparison with the current proverb (Meza 85b): אסתירא בלגינא קישׁ קישׁ קריא, a stater in a flaggon cries Kish, Kish, i.e., makes much clatter. In the heart of the understanding wisdom rests, i.e., remains silent and still, for the understanding feels himself personally happy in its possession, endeavours always the more to deepen it, and lets it operate within; on the contrary, wisdom in the heart of fools makes itself manifest: they a…

Observe, 1. Modesty is the badge of wisdom. He that is truly wise hides his treasure, so as not to boast of it (Mat 13:44), though he does not hide his talent, so as not to trade with it. His wisdom rests in his heart; he digests what he knows, and has it ready to him, but does not unseasonably talk of it and make a noise with it. The heart is the seat of the affections, and there wisdom must rest in the practical love of it, and not swim in the head. 2. Openness and ostentation are a mark of folly. If fools have a little smattering of knowledge, they take all occasions, though very foreign, to produce it, and bring it in by head and shoulders. Or the folly that is in the midst of fools is made known by their forwardness to talk. Many a foolish man takes more pains to show his folly than a wise man thinks it worth his while to take to show his wisdom.
