וְהָיָ֗ה כַּֽחֲלוֹם֙ חֲז֣וֹן לַ֔יְלָה הֲמוֹן֙ כָּל־הַגּוֹיִ֔ם הַצֹּבְאִ֖ים עַל־אֲרִיאֵ֑ל וְכָל־צֹבֶ֙יהָ֙ וּמְצֹ֣דָתָ֔הּ וְהַמְּצִיקִ֖ים לָֽהּ׃
И множество всех народов, которые воюют против Ариэля, даже вся эта война против нее, и ополчения вокруг нее, и те, кто ее огорчает, будет как сон, видение ночи.
Chizkuni
שש עגלות צב, “six covered wagons;” the expression צב, is derived from צבא, “army,” in the sense of mobilising.
Rashi
And I will encamp beside My house against a garrison I will encamp beside My house to protect it from those who set up a garrison and raiders, that they should not set these up against it. A similar word is used in (Isa. 29:7) “and all those stationed around her, and those who trap her.” It is also possible to interpret מִצָבָה as מִצָבָא, with an ‘alef’ [meaning against a host].
