Isaiah 34:5

5 For my sword is filled in heaven; lo! it shall come down on Idumea, and on the people of my slaying, to doom. (For my sword is made ready in heaven; lo! it shall come down upon Edom, and upon the people whom I will kill, for their doom/in judgement.)

Isaiah 34:5 Meaning and Commentary

Isaiah 34:5

For my sword shall be bathed in heaven
That is, the sword of the Lord, as it is called in the next verse ( Isaiah 34:6 ) , and it is he that is speaking; it designs the vengeance of the Lord, the punishment he will inflict on the wicked, said to be "bathed in heaven", because determined and prepared there; the allusion may be to the bathing of swords in some sort of liquor, to harden or brighten them, and so fit them for use. Kimchi renders it, "my sword" which is "in heaven shall be bathed", that is, in the blood of the slain; "heaven" may denote the whole Roman Papal jurisdiction, as it does the whole Roman Pagan empire in ( Revelation 12:7 ) and may design the principal men in it, those that are in the highest places and offices, in whom the sword of the Lord shall be first drenched, and be as it were satiated and inebriated with the blood of them: behold, it shall come down upon Idumea;
with great weight, force, and vengeance, having a commission from heaven to execute. Idumea is here particularly mentioned, because the Edomites were implacable enemies to the Jews, and so are here put for all the enemies of God's church and people, all the antichristian states, particularly Rome, which the Jews, as Jerom observes, understand by Edom or Idumea here: upon the people of my curse to judgment;
a very descriptive character of the Papists, the people of God's curse, and righteously so; those who have anathematized his people, and cursed them with bell, book, and candle, are anathematized by him, devoted to destruction, and doomed to be accursed, sentenced to ruin, and on whom judgment shall pass, and shall be executed; they shall hear, "go, ye cursed", both here and hereafter, at the fall of Babylon, and at the general judgment. The Targum is,

``because my sword is revealed in heaven; behold, upon Edom it is revealed, and upon the people whom I have condemned to judgment.''

Isaiah 34:5 In-Context

3 The slain men of them shall be cast forth, and stink shall ascend of the carrions of them; [the] hills shall flow of the blood of them. (Their dead shall be thrown forth, and the stink shall go up from their corpses; the hills shall flow with their blood.)

4 And all the chivalry of (the) heavens shall fail, and (the) heavens shall be folded together as a book, and all the knighthood of those shall float down, as the leaf of a vinery and of a fig tree falleth down. (And all the host of heaven shall fail, and the heavens shall be folded up like a book, and all their host shall float down like the leaf of a vine, and like the fig of a fig tree, that falleth down.)

5 For my sword is filled in heaven; lo! it shall come down on Idumea, and on the people of my slaying, to doom. (For my sword is made ready in heaven; lo! it shall come down upon Edom, and upon the people whom I will kill, for their doom/in judgement.)

6 The sword of the Lord is filled of blood, it is made fat of the inner fatness of the blood of lambs and of bucks of goats, of the blood of rams full of marrow (The sword of the Lord is filled with blood, and it is made fat with inner fatness, yea, with the blood of lambs and of goat bucks, and with the fat from the kidneys of rams); for why the slain sacrifice of the Lord is in Bozrah, and great slaying is in the land of Edom.

7 And unicorns shall go down with them, and bulls with them that be mighty (And wild oxen shall go down with them, and bulls with other mighty beasts); the land of them shall be filled with blood, and the earth of them with [the] inner fatness of fat beasts;
