יָבֵ֤שׁ חָצִיר֙ נָ֣בֵֽל צִ֔יץ כִּ֛י ר֥וּחַ יְהוָ֖ה נָ֣שְׁבָה בּ֑וֹ אָכֵ֥ן חָצִ֖יר הָעָֽם׃
The grass withereth, the flower fadeth; Because the breath of the LORD bloweth upon it— Surely the people is grass.
Ibn Ezra on Isaiah
חציר Grass. The fresh grass; the word has the same meaning in Arabic.17خَضِرَ Viruit, خَضِرٌ Viridis. (Freytag, Lex. Arab. Lat.)
Ibn Ezra on Isaiah
נשבה Bloweth. Comp. וישב and he drove away (Gen. 15:11), though of a different conjugation.18נשבה is the third person feminine part, of Kal; וישב is the third person masculine future (with ו conversive) of Hiphil.
