Isaiah 34:3-8

Their slain will be cast out, the stench of their corpses will rise, and the mountains will stream with their blood. The heavenly powers will fade away to nothing, and the heavens will be rolled up like a scroll. All their mighty host will wither as leaves fall from a withered vine or fruit from a withering fig tree. The Lord says: “Indeed, my judgment-sword has appeared in the heavens, and when it has drunk its fill, you will see it descend on the people of Edom, those whom I have doomed to judgment.” Lord YAHWEH has a judgment-sword dripping with blood. It is smeared with fat, dripping with the blood of lambs and goats, and covered with the fat of rams’ kidneys. Lord YAHWEH has a sacrifice in Bozrah and a great slaughter in the land of Edom. Cattle and young bulls will also be slain; their land will be drenched with blood and the dust soaked with fat. For Lord YAHWEH has a day of vengeance, a year of vindication for Zion’s cause.
