And the multitude of all the nations - The Assyrians, and their allied hosts.

And her munition - Her fortresses, castles, places of strength 2 Samuel 5:7; Ecclesiastes 9:14; Ezekiel 19:9.

Shall be as a dream of a night vision - In a dream we seem to see the objects of which we think as really as when awake, and hence, they are called visions, and visions of the night Genesis 46:2; Job 4:13; Job 7:14; Daniel 2:28; Daniel 4:5; Daniel 7:1, Daniel 7:7, Daniel 7:13, Daniel 7:15. The specific idea here is not that of the "suddenness" with which objects seen in a dream appear and then vanish, but it is that which occurs in Isaiah 29:8, of one who dreams of eating and drinking, but who awakes, and is hungry and thirsty still. So it was with the Assyrian. He had set his heart on the wealth of Jerusalem. He had earnestly desired to possess that city - as a hungry man desires to satisfy the cravings of his appetite. But it would be like the vision of the night; and on that fatal morning on which he should awake from his fond dream Isaiah 37:36, he would find all his hopes dissipated, and the longcherished desire of his soul unsatisfied still.

As a dream - This is the beginning of the comparison, which is pursued and applied in the next verse. Sennacherib and his mighty army are not compared to a dream because of their sudden disappearance; but the disappointment of their eager hopes is compared to what happens to a hungry and thirsty man, when he awakes from a dream in which fancy had presented to him meat and drink in abundance, and finds it nothing but a vain illusion. The comparison is elegant and beautiful in the highest degree, well wrought up, and perfectly suited to the end proposed. The image is extremely natural, but not obvious: it appeals to our inward feelings, not to our outward senses; and is applied to an event in its concomitant circumstances exactly similar, but in its nature totally different. See De S. Poes. Hebr. Praelect. 12. For beauty and ingenuity it may fairly come in competition with one of the most elegant of Virgil, greatly improved from Homer, Iliad 22:199, where he has applied to a different purpose, but not so happily, the same image of the ineffectual working of imagination in a dream: -

Ac veluti in somnis, oculos ubi languida pressit

Nocte quies, necquicquam avidos extendere cursus

Velle videmur, et in mediis conatibus aegri

Succidimus; non lingua valet, non corpore notae

Sufficiunt vires, nec vox, nec verba sequuntur.

Aen., 12:908.

"And as, when slumber seals the closing sight,

The sick wild fancy labors in the night;

Some dreadful visionary foe we shun

With airy strides, but strive in vain to run;

In vain our baffled limbs their powers essay;

We faint, we struggle, sink, and fall away;

Drain'd of our strength, we neither fight nor fly,

continued...

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.

And the {f} multitude of all the nations that fight against Ariel, even all that fight against her and her strong hold, and that distress her, shall be as a dream of a night vision.

(f) The enemies that I will bring to destroy you, and that which you place your vain trust in will come at unawares even as a dream in the night. Some read as if this was a comfort to the Church for the destruction of their enemies.

7. munition-fortress.

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.
