אָבַ֥ל תִּיר֖וֹשׁ אֻמְלְלָה־גָ֑פֶן נֶאֶנְח֖וּ כָּל־שִׂמְחֵי־לֵֽב׃
The new wine faileth, the vine fadeth; All the merry-hearted do sigh.
Ibn Ezra on Isaiah
The new wine mourneth, etc. Because there is none to dress the vine and to dig the ground.
Ibn Ezra on Isaiah
The merry-hearted. For wine maketh glad the heart (Ps. 104:15)
