Proverbs 19:13 New English Translation

¹³A foolish child^[a] is the ruin of his father,
and a contentious wife^[b] is like^[c] a constant dripping.^[d]

Proverbs 19:13 tn Heb “a foolish son” (so KJV, NAB, NIV, CEV); NRSV “a stupid child.”
Proverbs 19:13 tn Heb “the contentions of a wife” (so KJV, NASB); NAB “the nagging of a wife.” The genitive could be interpreted (1) as genitive of source or subjective genitive—she is quarreling; or (2) it could be a genitive of specification, making the word “contentions” a modifier, as in the present translation.
Proverbs 19:13 tn Heb “is a constant dripping.” The term “like” does not appear in the Hebrew but is supplied in the translation for the sake of clarity. The metaphor pictures water dropping (perhaps rain through the roof, cf. NRSV, CEV) in a continuous flow: It is annoying and irritating (e.g., Prov 27:15-16).
Proverbs 19:13 tc The LXX makes this moralistic statement for 13b: “vows paid out of hire of a harlot are not pure.” It is not based on the MT and attempts to reconstruct a text using this have been unsuccessful.
