ישעיהו כט:ה פירוש: רש״י ואבן עזרא

And the multitude of your foreigners shall be like fine dust The army of Sennacherib, which will be consumed by fire and will become dust.

כאבק דק Like small dust. Some word must be supplied, because of אבק being in the construct state.¹¹Our editions have כְאָבָק, in the absolute state; I. E. read כַאֲבַק as the dust of, and requires the supplement of a genitive. The translation of the sentence according to I. E. would be, and the multitude of thy strangers shall be small as the dust of.

and it shall be this thing.
