דֶּ֣לֶף ט֭וֹרֵד בְּי֣וֹם סַגְרִ֑יר וְאֵ֥שֶׁת מדונים [מִ֝דְיָנִ֗ים] נִשְׁתָּוָֽה׃
Une gouttière qui se déverse par un jour d’orage et une femme acariâtre, c’est tout un.
Ibn Ezra
the earnings of a harlot. The word earnings [Hebrew: etnan] comes from the word “gift” [Hebrew: mattan], with an extraneous ’alef , and a repeated nun (like the peh in “her adulteries” [Hosea 2: 4] and the resh in “torrential” [Proverbs 27: 15]). It denotes that which the prostitute took (i.e., that which was given her by the men who engaged in prostitution with her).
Ibn Ezra
שוה He hath made plain. Derived from שוה equal; comp. נשתוה alike (Prov. 27:15).
