Proverbs 27:15 New English Translation

¹⁵A continual dripping on a rainy day—
a contentious wife^[a] makes herself like that.^[b]

Proverbs 27:15 tn Heb “a wife of contentions” (an attributive genitive). Cf. NAB, NIV “a quarrelsome wife”; NLT “a nagging wife.”
Proverbs 27:15 tc The form נִשְׁתָּוָה (nishtavah) may be a rare Nitpael form or a scribal error for the Niphal of the root שָׁוָה (shavah, “to be like, comparable to.” BDB classifies it as a Nitpael perfect from (BDB 1001 s.v. I שָׁוָה) with metathesis before the sibilant, a phonetic factor also known in the Hitpael. HALOT suggests that the metathesis is a scribal error such that the form should be נִשְׁוָתָה (nishvatah), a standard Niphal perfect third feminine singular. Either form should be understood with a reflexive meaning. She “makes herself like” an annoying dripping. The LXX concocts a further illustration: “Drops drive a man out of his house on a wintry day; so a railing woman also drives him out of his own house.”tn The word “that” does not appear in the Hebrew. This is structured like other metaphorical proverbs (e.g. 26:7, 9, 10) whose first line begins without the word “like,” but still functions as a comparison for the second line which begins with the conjunction vav (“and”). These are often translated as similes, using “like… so….” In this case the verb has a semantic meaning of “like,” so that has not been added at the beginning to avoid redundancy in English.
