אֵ֥יךְ לֹֽא־עֻזְּבָ֖ה עִ֣יר תהלה [תְּהִלָּ֑ת] קִרְיַ֖ת מְשׂוֹשִֽׂי׃
װי ניט פֿאַרשוֹינט געװאָרן איז דער גערימטער כּרַך, די שטאָט פֿון מײַן פֿרײד!
Rashi
“How was...not fortified” It was not filled with earth around its wall to strengthen the wall. Cf. “And they fortified (ויעזבוּ) Jerusalem up to the wall” (Neh. 3:8). It can also be interpreted: Why was it not forsaken by this evil, that the evil should not come upon it?
