1 tn Heb “soft answer.” The adjective רַּךְ (rakh, “soft; tender; gentle”; BDB 940 s.v.) is more than a mild response; it is conciliatory, an answer that restores good temper and reasonableness (W. McKane, Proverbs [OTL], 477). Gideon illustrates this kind of answer (Judg 8:1-3) that brings peace.
2 tn Heb “word of harshness”; KJV “grievous words.” The noun עֶצֶב (’etsev, “pain, hurt”) functions as an attributive genitive. The term עֶצֶב refers to something that causes pain (BDB 780 s.v. I עֶצֶב). For example, Jephthah’s harsh answer led to war (Judg 12:1-6).
3 tn Heb “raises anger.” A common response to painful words is to let one’s temper flare up.
4 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.
5 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.
6 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”).
