Isaiah 34:5

3Their slain also shall be cast out, and their stink shall come up out of their carcases, and the mountains shall be melted with their blood.

4And all the host of heaven shall be dissolved, and the heavens shall be rolled together as a scroll: and all their host shall fall down, as the leaf falleth off from the vine, and as a falling fig from the fig tree.

5For my sword shall be bathed in heaven: behold, it shall come down upon Idumea, and upon the people of my curse, to judgment.

6The sword of the LORD is filled with blood, it is made fat with fatness, and with the blood of lambs and goats, with the fat of the kidneys of rams: for the LORD hath a sacrifice in Bozrah, and a great slaughter in the land of Idumea.

7And the unicorns shall come down with them, and the bullocks with the bulls; and their land shall be soaked with blood, and their dust made fat with fatness.
