וַֽיַּאֲמִ֛ינוּ אַנְשֵׁ֥י נִֽינְוֵ֖ה בֵּֽאלֹהִ֑ים וַיִּקְרְאוּ־צוֹם֙ וַיִּלְבְּשׁ֣וּ שַׂקִּ֔ים מִגְּדוֹלָ֖ם וְעַד־קְטַנָּֽם׃
니느웨 백성이 하나님을 믿고 금식을 선포하고 무론 대소하고 굵은 베를 입은지라
Ibn Ezra
that "overturned" [means] that it would overturn [itself] from [doing] it's evil actions, and this interpretation is not correct; [rather] the [interpretation of the] matter is only like [the verse]: "For a moment I speak [of a nation to be destroyed and smashed...]" (Jeremiah 18:7)
