Isaiah 34:5

“For my sword shall be bathed in heaven, &c.] That is, the sword of the Lord, as it is called in the next verse (<233406>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 (<661207>Revelation 12:7) and may design the principal…”

“sword-- (Jer 46:10). Or else, knife for sacrifice for God does not here appear as a warrior with His sword, but as one about to sacrifice victims doomed to slaughter [VITRINGA]. (Eze 39:17). bathed--rather "intoxicated," namely, with anger (so Deu 32:42). "In heaven" implies the place where God's purpose of wrath is formed in antithesis to its "coming down" in the next clause. Idumea--originally extending from the Dead Sea to the Red Sea; afterwards they obtained possession of the country east of Moab, of which Bozrah was capital. Petra or Selah, called Joktheel (Kg2 14:7), was capital of South Edom (see on Isa 16:1). David subjugated Edom (Sa2 8:13-14). Under Jehoram they regained…”

“For my sword shall be bathed in heaven - A sword is an instrument of vengeance, and is often so used in the Scriptures, because it was often employed in capital punishments (see the note at Isaiah 27:1). This passage bas given much perplexity to commentators, on account of the apparent want of meaning of the expression that the sword would be bathed in heaven. Lowth reads it: For my sword is made bare in the heavens; Following in this the Chaldee which reads תתגלי tı̂thgallı̂y, ‘shall be revealed.’ But there is no authority from manuscripts for this change in the Hebrew text. The Vulgate renders it, Quoniam inebriatus est in coelo gladius meuse - ‘My sword is intoxicated in heaven.’ The…”

“Bathed - In the blood of these people. Heaven - Where God dwells; in which this is said to be done, because it was there decreed and appointed. Idumea - Upon the Edomites, who, tho' they were nearly related to the Israelites, yet were their implacable enemies. But these are named for all the enemies of God's church, of whom they were an eminent type. The people - Whom I have cursed, and devoted to utter destruction, as the word properly signifies. Isaiah 34:6”

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

“my sword: Deu 32:14, Deu 32:42; Psa 17:13; Jer 46:10, Jer 47:6; Eze 21:3-5, Eze 21:9-11; Zep 2:12; Rev 1:16 upon Idumea: Isa 63:1; Psa 137:7; Jer. 49:7-22; Eze 25:12-14; Amo 1:11, Amo 1:12; Oba 1:1-9; Mal 1:4 the people: Deu 27:15-26, Deu 29:18-21; Mat 25:41; Co1 16:22; Gal 3:10; Pe2 2:14 Isaiah 34:6”

“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,…”
