(7) Against her and her munition.--The word is a rare one, but probably stands here for the new fortifications by which Uzziah and Hezekiah had defended Jerusalem.

Verse 7. - Her munition; i.e. her defenses the walls and towers in which she put her trust (comp. ver. 3). As a dream of a night vision. "The baseless fabric of a vision," when it has once passed by, "leaves not wrack behind." The entire host of the "terrible ones" would melt away and disappear, as a night vision before the light of day - it would dissolve into nothing, vanish, leave no trace.

29:1-8 Ariel may signify the altar of burnt-offerings. Let Jerusalem know that outward religious services will not make men free from judgements. Hypocrites never can please God, nor make their peace with him. God had often and long, by a host of angels, encamped round about Jerusalem for protection and deliverance; but now he fought against it. Proud looks and proud language shall be brought down by humbling providences. The destruction of Jerusalem's enemies is foretold. The army of Sennacherib went as a dream; and thus the multitudes, that through successive ages fight against God's altar and worship, shall fall. Speedily will sinners awake from their soothing dreams in the pains of hell.And the multitude of all the nations that fight against Ariel,.... The Roman army, which consisted of men of all nations, that fought against Jerusalem; the city in which was the altar, as the Targum paraphrases it:

even all that fight against her, and her munition, and that distress her; that besieged it, and endeavoured to demolish its walls, towns, and fortifications, as they did:

shall be as a dream of a night vision: meaning either that the Roman empire should quickly fall, and pass away, and come to nothing, like a dream in the night, as it soon began to decay after the destruction of Jerusalem, and also the Pagan religion in it; or that the Roman army would be disappointed at the taking of the city, expecting to find much riches, and a great spoil, and should not; and so be like a man that dreams, and fancies he is in the possession of what he craves, but, when he awakes, finds he has got nothing. This is more largely exemplified in the following verse Isaiah 29:8.
