וְהָיָ֗ה כַּֽחֲלוֹם֙ חֲז֣וֹן לַ֔יְלָה הֲמוֹן֙ כָּל־הַגּוֹיִ֔ם הַצֹּבְאִ֖ים עַל־אֲרִיאֵ֑ל וְכָל־צֹבֶ֙יהָ֙ וּמְצֹ֣דָתָ֔הּ וְהַמְּצִיקִ֖ים לָֽהּ׃
And the multitude of all the nations that war against Ariel, Even all that war against her, and the bulwarks about her, and they that distress her, Shall be as a dream, a vision of the night.
Rashi on Isaiah
And shall be like a dream that one imagines that he saw, yet he did not see, so will this multitude of all the nations contemplate to conquer, but they will not succeed.
Ibn Ezra on Isaiah
Shall be as a dream, etc. It will be like a dream; it causes man to see things by night, which, when he awakes, are no more. This was to be the case with the Assyrian camp.
Rashi on Isaiah
those stationed around her who set up against her a garrison and raiders called cenbel in O.F., as it is stated regarding Saul (I Sam. 14: 15): “The garrison and the raiders trembled.”
