Jesaja 34:5

If we bear this in mind, we shall not be surprised that the prophet gives the following reason for the passing away of the present heavens. "For my sword has become intoxicated in the heaven; behold, it comes down upon Edom, and upon the people of my ban to judgment. The sword of Jehovah fills itself with blood, is fattened with fat, with blood of lambs and he-goats, with kidney-fat of rams; for Jehovah has a sacrifice in Bozrah, and a great slaughter in the land of Edom. And buffaloes fall with them, and bullocks together with bulls; and their land become intoxicated with blood, and their dust fattened with fat." Just as in chapter 63 Jehovah is represented as a treader of the wine-press, and the nations as the grapes; so here He is represented as offering sacrifice, and the nations as the animals offered (zebhach: cf., Zep 1:7; Jer 46:10); Eze 39:17.: all three passages founded upon this). Jehovah does not appear here in person as judge, as He does there, but His sword appears; just as in Gen 3:24, the "sword which turned every way" is mentioned as an independent power standing by the side of the cherub. The sword is His executioner, which has no sooner drunk deeply of wrath in heaven, i.e., in the immediate sphere of the Deity (rivvethâh, an intensive form of the kal, like pittēăch, Isa 48:8; Ewald, 120, d), than it comes down in wild intoxication upon Edom, the people of the ban of Jehovah, i.e., the people upon whom He has laid the ban, and there, as His instrument of punishment, fills itself with blood, and fattens itself with fat. הדּשׁנה is the hothpaal = התדּשׁנה, with the ת of the preformative syllable assimilated (compare הזּכּוּ in Isa 1:16, and אדּמּה in Isa 14:14). The penultimate has the tone, the nâh being treated as in the plural forms of the future…

In this chapter we have the fatal doom of all the nations that are enemies to God's church and people, though Edom only is mentioned, because of the old enmity of Esau to Jacob, which was typical, as much as that more ancient enmity of Cain to Abel, and flowed from the original enmity of the serpent to the seed of the woman. It is probable that this prophecy had its accomplishment in the great desolations made by the Assyrian army first, or rather by Nebuchadnezzar's army some time after, among those nations that were neighbours to Israel and had been in some way or other injurious to them. That mighty conqueror took a pride in shedding blood, and laying countries waste, and therein, quite beyond his design, he was fulfilling what God here threatened against his and his people's enemies. But we have reason to think it is intended as a denunciation of the wrath of God against all those who fight against the interests of his kingdom among men, that it has its frequent accomplishment in the havoc made by the wars of the nations and other desolating judgments, and will have its full accomplishment in the final dissolution of all things at the day of judgment and perdition of ungodly men. Here is, I. A demand of universal attention (Isa 34:1). II. A direful scene of blood and confusion presented (Isa 34:2-7). III. The reason given for these judgments (Isa 34:8). IV. The continuance of this desolation, the country being made like the lake of Sodom (Isa 34:9, Isa 34:10), and the cities abandoned to wild beasts and melancholy fowls (Isa 34:11-15). V. The solemn ratification of all this (Isa 34:16, Isa 34:17). Let us hear, and fear.

34:5 Edom here represents what all the nations would experience, just as Moab was singled out in ch 25.
