Isaiah 34:2,3 - Joseph Benson’s Commentary on the Old and New Testaments

For the indignation of the Lord is upon all nations Not only upon the Assyrians, and those nations which are confederate with them in their expedition against Judea, but upon all other enemies of my people. He hath utterly destroyed them He will infallibly destroy all of them. Their slain also shall be cast out Into the fields, where they shall lie unburied, and be left a prey to ravenous beasts and birds. In which words he implies, either that such vast numbers would be slain, that the survivers would not be able to find time or place to bury them, or that they should be held in such contempt and abhorrence that none would be inclined to do them that office: and the mountains About Jerusalem, where they are supposed to be gathered to fight against her, like the Assyrians; shall be melted with their blood Shall be covered with their blood, which shall flow down abundantly from them with great force, and dissolve, and carry down with it a part of the soil of the mountains, as great showers of rain frequently do. This sentence upon the nations, which thus exhibits a kind of general judgment, to be executed upon the enemies of God and his people, by the sword of God, is sufficient to strike terror into every hearer.
