15:14 The discerning heart seeks knowledge,
but the mouth of fools feeds on folly. 1
15:21 Folly is a joy to one who lacks sense, 2
but one who has understanding 3 follows an upright course. 4
1 tn The idea expressed in the second colon does not make a strong parallelism with the first with its emphasis on seeking knowledge. Its poetic image of feeding (a hypocatastasis) would signify the acquisition of folly – the fool has an appetite for it. D. W. Thomas suggests the change of one letter, ר (resh) to ד (dalet), to obtain a reading יִדְעֶה (yid’eh); this he then connects to an Arabic root da`a with the meaning “sought, demanded” to form what he thinks is a better parallel (“Textual and Philological Notes on Some Passages in the Book of Proverbs,” VTSup 3 [1955]: 285). But even though the parallelism is not as precise as some would prefer, there is insufficient warrant for such a change.
2 tn The Hebrew text reads לַחֲסַר־לֵב (lakhasar-lev, “to one who lacks heart”). The Hebrew term “heart” represents the mind, the place where proper decisions are made (cf. NIV “judgment”). The one who has not developed this ability to make proper choices finds great delight in folly.
3 tn Heb “a man of understanding” (so KJV, NIV); NLT “a sensible person.”
4 tn The Hebrew construction is יְיַשֶּׁר־לָכֶת (yÿyasher-lakhet, “makes straight [to] go”). This is a verbal hendiadys, in which the first verb, the Piel imperfect, becomes adverbial, and the second form, the infinitive construct of הָלַךְ, halakh, becomes the main verb: “goes straight ahead” (cf. NRSV).
