Isaiah 34:6-8

The sword of Jehovah is filled with blood, it is made fat with fatness, with the blood of lambs and goats, with the fat of the kidneys of rams; for Jehovah hath a sacrifice in Bozrah, and a great slaughter in the land of Edom. And the wild-oxen shall come down with them, and the bullocks with the bulls: and their land shall be drunken with blood, and their dust made fat with fatness. For Jehovah hath a day of vengeance, a year of recompense for the cause of Zion.
