(5) My sword shall be bathed in heaven . . .--Literally, hath drunk to the full. The words find an echo in Deuteronomy 32:41-42, and Jeremiah 46:10. There, however, the sword is soaked, or made drunk with blood. Here it is "bathed in heaven," and this seems to require a different meaning. We read in Greek poets, of the "dippings" by which steel was tempered. May not the "bathing" of Isaiah have a like significance?

It shall come down upon Idumea . . .--Better, for Edom, . . . here and in the next verse. No reason can be assigned for this exceptional introduction of the Greek form.

Verse 5. - My sword shall be bathed in heaven; rather, has been bathed, or has been made drunken (ἐνεθύσθη, LXX.) in heaven. Some suppose a reference to the old" war in heaven," when the sword of Divine justice was drawn against the devil and his angels. Others regard the sword now to be used against the Idumeans as first, in heaven, "made drunken" with the Divine anger. It shall come down upon Idumea (comp. Isaiah 63:1-6). The Edomites first showed themselves enemies of Israel when they refused to allow the Israelites, under Moses, "a passage through their border" (Numbers 20:14-21). David subdued them (2 Samuel 9:14); but they revolted from Jehoram (2 Chronicles 21:8-10), and were thenceforward among the most bitter adversaries of the southern kingdom. They "smote Judah" in the reign of Ahaz (2 Chronicles 28:17), and were always ready to "shed the blood of the children of Israel by the force of the sword in the time of their calamity" (Ezekiel 35:5). Amos speaks of them very much in the same tone as Isaiah (Amos 1:11, 12). They ultimately "filled up the measure of their iniquities" by open rejoicing when Jerusalem was destroyed, and the people led away captive by Nebuchadnezzar (Psalm 137:7; Obadiah 1:10-14; Lamentations 4:21, 22; Ezekiel 35:10-13). In the present passage we must regard the Edomites as representative of the enemies of God's people generally (see the introductory paragraph). The people of my curse; i.e. "the people on whom I have laid a curse" - the Edomites. Esau was to "serve" Jacob (Genesis 25:23; Genesis 27:40), Edom to be "a possession" for Judah (Numbers 24:18). God had said of Edom, probably before Isaiah uttered the present prophecy, "For three transgressions of Edom, and for four, I will not turn away the punishment thereof... but I will send a fire upon Teman, which shall devour the palaces of Bozrah" (Amos 1:11, 12). Thus Edom was under a curse.

34:1-8 Here is a prophecy of the wars of the Lord, all which are both righteous and successful. All nations are concerned. And as they have all had the benefit of his patience, so all must expect to feel his resentment. The description of bloodshed suggests tremendous ideas of the Divine judgments. Idumea here denotes the nations at enmity with the church; also the kingdom of antichrist. Our thoughts cannot reach the horrors of that awful season, to those found opposing the church of Christ. There is a time fixed in the Divine counsels for the deliverance of the church, and the destruction of her enemies. We must patiently wait till then, and judge nothing before the time. Through Christ, mercy is exercised to every believer, consistently with justice, and his name is glorified.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.''
