Isaiah 34:5-6

For My sword is satiated in heaven, Behold it shall descend for judgment upon Edom And upon the people whom I have devoted to destruction. The sword of the LORD is filled with blood, It is sated with fat, with the blood of lambs and goats, With the fat of the kidneys of rams. For the LORD has a sacrifice in Bozrah And a great slaughter in the land of Edom.
