Jeschijahu 46:8 Kommentar: Rashi & Ibn Ezra

Remember this what I wish to say.

והתאששו According to some And be founded ; comp. אשיותיה her foundations (Jer. 1. 15) and אושיא walls (Ezr. 4:12). R. Hai deriving it from אש fire explains והתאוששו be burnt. R. Saadiah derives it also from אֵשׁ, but explains it: be flamed; comp. this word was in mine heart as a burning fire (Jer. 20:9).⁵The difference between the two explanations, that of R. Hai and that of R. Saadiah, is, that the former derives it from אש fire in its literal sense, as a destructive element, the other from אש fire in a figurative sense, as the incentive to actions. Bring again to mind this thing.^5aI. E. supplies ואת mentioned in the first sentence. This thing refers to the nature of the idols described in the preceding verses.

and strengthen yourselves Heb. וְהִתְאשָׁשׁוּ. Comp. (supra 16: 7) “For the walls (לַאֲשִׁישֵׁי) of Kir-hareseth.”
