And all the armies of heaven shall fade away. Isaiah employs an exaggerated style, as other prophets are accustomed to do, in order to represent vividly the dreadful nature of the judgment of God, and to make an impression on men's hearts that were dull and sluggish; for otherwise his discourse would have been deficient in energy, and would have had little influence on careless men. He therefore adds that "the stars" themselves, amidst such slaughter, shall gather blackness as if they were ready to faint, and he does so in order to show more fully that it will be a mournful calamity. In like manner, as in a dark and troubled sky, the clouds appear to be folded together, the sun and stars to grow pale and, as it were, to faint, and all those heavenly bodies to totter and give tokens of ruin; he declares that thus will it happen at that time, and that everything shall be full of the saddest lamentation. These statements must be understood to relate to men's apprehension, for heaven is not moved out of its place; but when the Lord gives manifestations of his anger, we are terrified as if the Lord folded up or threw down the heavens; not that anything of this kind takes place in heaven, but he speaks to careless men, who needed to be addressed in this manner, that they might not imagine the subject to be trivial or a fit subject of scorn. "You will be seized with such terror that you shall think that the sky is falling down on your heads." It is the just punishment of indifference, that wicked men, who are not moved by any fear of God, dread their own shadow, and tremble "at the rustling of a falling leaf," (Leviticus 26:36,) as much as if the sun were falling from heaven. Yet it also denotes a dreadful revolution of affairs, by which everything shall be subverted and disturbed.

And all the host of heaven - On the word 'host' (צבא tsâbâ'), see the note at Isaiah 1:9. The heavenly bodies often represent kings and princes (compare the note at Isaiah 24:21).
Shall be dissolved - (ינמקוּ venâmaqqû. This figure Vitringa supposes to be taken from the common prejudice by which the stars appear to be crystals, or gems, set in the azure vault of heaven, which may melt and flow down by the application of heat. The sense is, that the princes and nobles who had opposed God and his people would be destroyed, as if the sparkling stars, like gems, should melt in the heavens, and flow down to the earth.
And the heavens shall be rolled together as a scroll - The word 'scroll' here (ספר sêpher) means a roll, or a book. Books were made of parchment, leaves, etc., and were rolled together instead of being bound, as they are with us. The figure here is taken from what strikes the eye, that the heaven above us is "an expanse" (רקיע râqı̂ya‛) Genesis 1:8; Psalm 104:2,) which is spread out; and which might be rolled together, and thus pass away. It is possible that there may be a reference also to the fact, that in a storm, when the sky is filled with dark rolling clouds, the heavens seem to be rolled together, and to be passing away. The sense is, that there would be great destruction among those high in office and in power - a destruction that would be well represented by the rolling up of the firmament, and the destruction of the visible heavens and their host, and by leaving the world to ruin and to night.
And all their host shall fall down - That is, their stars; either by being as it were melted, or by the fact that the expanse in which they are apparently located would be rolled up and removed, and there being no fixtures for them they would fall. The same image occurs in Revelation 6:13. One somewhat similar occurs in Virgil, Georg. i. 365ff.
As the leaf falleth off from the vine - That is, in a storm, or when violently shaken.

And all the host of heaven See note on Isaiah 24:21, and De Sacra Poesi Hebraeorum, Prael. ix.

And all the host of heaven (c) shall be dissolved, and the heavens shall be rolled together as a scroll: and all their hosts shall fall down, as the leaf falleth from the vine, and as a falling [fig] from the fig tree.
(c) He speaks this in respect to man's judgment, who in great fear and horrible troubles, think that heaven and earth perishes.

And all the hosts of heaven shall be dissolved,.... "Pine away" (i), as with sickness, grow languid, become obscure, lose their light, and be turned into blood and darkness; this figure is used to express the horror of this calamity, as if the very heavens themselves, and the sun, and moon, and stars, were affected with it; see Isaiah 13:10.
and the heavens shall be rolled gether as a scroll; a book, or volume, which when rolled up, one letter of it could not be read; and it was the manner formerly of making and writing books in the form of a roll; hence the word volume; and here it signifies that there should be such a change in the heavens, as that not a star should be seen, much less the sun or moon; and may signify the utter removal and abolition of all dignities and offices, supreme and subordinate, civil and ecclesiastical, in the whole Roman jurisdiction; thus the destruction of Rome Pagan is described in Revelation 6:14 as the destruction of Rome Papal is here; from whence the language seems to be borrowed:
and all their host shall fall down, as the leaf falleth off from the vine, and as a falling fig from the fig tree; that is, the stars should fall down: by whom may be meant persons in office, that made a considerable figure; who shall fall from their stations, in which they shone with much splendour and grandeur, as leaves fall from trees in autumn, particularly the vine; or as unripe and rotten figs fall from the fig tree when shaken by a violent wind; the same metaphor is used in Revelation 6:13.
(i) "tabescet", Vatablus; "centabescet", Junius & Tremellius, Piscator; "contabescent", Cocceius, Gataker.

(Psalm 102:26; Joel 2:31; Joel 3:15; Matthew 24:29).
dissolved-- (2-Peter 3:10-12). Violent convulsions of nature are in Scripture made the images of great changes in the human world (Isaiah 24:19-21), and shall literally accompany them at the winding up of the present dispensation.
scroll--Books were in those days sheets of parchment rolled together (Revelation 6:14).
fall down--The stars shall fall when the heavens in which they are fixed pass away.
fig tree-- (Revelation 6:13).

The judgment foretold by Isaiah also belongs to the last things; for it takes place in connection with the simultaneous destruction of the present heaven and the present earth."And all the host of the heavens moulder away, and the heavens are rolled up like a scroll, and all their host withers as a leaf withers away from the vine, and like withered leaves from the fig-tree" (Nâmaq, to be dissolved into powdered mother (Isaiah 3:24; Isaiah 5:24); nâgōl (for nâgal, like nâzōl in Isaiah 63:19; Isaiah 64:2, and nârōts in Ecclesiastes 12:6), to be rolled up - a term applied to the cylindrical book-scroll. The heaven, that is to say, the present system of the universe, breaks up into atoms, and is rolled up like a book that has been read through; and the stars fall down as a withered leaf falls from a vine, when it is moved by even the lightest breeze, or like the withered leaves shaken from the fig-tree. The expressions are so strong, that they cannot be understood in any other sense than as relating to the end of the world (Isaiah 65:17; Isaiah 66:22; compare Matthew 24:29). It is not sufficient to say that "the stars appear to fall to the earth," though even Vitringa gives this explanation.
When we look, however, at the following kı̄ (for), it undoubtedly appears strange that the prophet should foretell the passing away of the heavens, simply because Jehovah judges Edom. But Edom stands here as the representative of all powers that are hostile to the church of God as such, and therefore expresses an idea of the deepest and widest cosmical signification (as Isaiah 24:21 clearly shows). And it is not only a doctrine of Isaiah himself, but a biblical doctrine universally, that God will destroy the present world as soon as the measure of the sin which culminates in unbelief, and in the persecution of the congregation of the faithful, shall be really full.

Dissolved - The sun, moon, and stars. So great shall be the confusion and consternation of mankind, as if all the frame of the creation were broken into pieces. It is usual for prophetic writers, both in the Old and New Testament, to represent great and general calamities, in such words and phrases, as properly agree to the day of judgment; as on the contrary, the glorious deliverances of God's people, in such expressions, as properly agree to the resurrection from the dead.
