15:2 The tongue of the wise 1 treats knowledge correctly, 2
but the mouth of the fool spouts out 3 folly.
15:28 The heart of the righteous considers 4 how 5 to answer, 6
but the mouth of the wicked pours out evil things. 7
1 sn The contrast is between the “tongue of the wise” and the “mouth of the fool.” Both expressions are metonymies of cause; the subject matter is what they say. How wise people are can be determined from what they say.
2 tn Or “makes knowledge acceptable” (so NASB). The verb תֵּיטִיב (tetiv, Hiphil imperfect of יָטַב [yatav, “to be good”]) can be translated “to make good” or “to treat in a good [or, excellent] way” (C. H. Toy, Proverbs [ICC], 303). M. Dahood, however, suggests emending the text to תֵּיטִיף (tetif) which is a cognate of נָטַף (nataf, “drip”), and translates “tongues of the sages drip with knowledge” (Proverbs and Northwest Semitic Philology, 32-33). But this change is gratuitous and unnecessary.
3 sn The Hiphil verb יַבִּיעַ (yabia’) means “to pour out; to emit; to cause to bubble; to belch forth.” The fool bursts out with reckless utterances (cf. TEV “spout nonsense”).
4 tn The verb יֶהְגֶּה (yehgeh) means “to muse; to meditate; to consider; to study.” It also involves planning, such as with the wicked “planning” a vain thing (Ps 2:1, which is contrasted with the righteous who “meditate” in the law [1:2]).
5 tn The word “how” is supplied in the translation for stylistic reasons.
6 tc The LXX reads: “the hearts of the righteous meditate faithfulness.”
7 sn The form is plural. What they say (the “mouth” is a metonymy of cause) is any range of harmful things.
