Isaiah 34:3

Shall be cast out into the fields, where they shall lie unburied, and be left for a prey to all ravenous birds and beasts; whereby he implies, either the vast numbers which shall be slain, so as they could not have time or place to bury them; or the curse of God upon them, and the people's contempt and abhorrency of them. The mountains about Jerusalem, where they are supposed to be gathered to fight against Jerusalem, as the Assyrians now were, and as other enemies afterward would be, Malachi 12:2, Malachi 14:2. Shall be melted with their blood; shall be filled with their blood, which shall run down abundantly from the mountains with great force, and dissolve and carry down part of the earth of the mountains with it, as great showers of rain frequently do.
