וְאֵין־קוֹרֵ֣א בְשִׁמְךָ֔ מִתְעוֹרֵ֖ר לְהַחֲזִ֣יק בָּ֑ךְ כִּֽי־הִסְתַּ֤רְתָּ פָנֶ֙יךָ֙ מִמֶּ֔נּוּ וַתְּמוּגֵ֖נוּ בְּיַד־עֲוֺנֵֽנוּ׃
Niemand ist, der deinen Namen anruft, der sich regte, an dir festzuhalten; denn verhüllt hast du dein Antlitz vor uns und lässt uns vergehen durch unsere Missetaten.
Ibn Ezra on Isaiah
מתעורר That stirreth up himself. It is an adjective.17Such a contraction is usually indicated by a Dagesh in the letter next to the one omitted; here the ב should have a Dagesh (וַנַּבֶּל Hiphil of נבל). The form can, however, be considered as regular if derived from בול; verbs פ״נ and ע״ו interchange sometimes; comp. סוך and נסך to anoint.
Rashi on Isaiah
and You caused us to wander Heb. וַתְּמוּגֵנוּ, You caused us to wander.
