Isaiah 34:6-8

The LORD has a sword; it is sated with blood; it is gorged 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, a great slaughter in the land of Edom. Wild oxen shall fall with them, and young steers with the mighty bulls. Their land shall drink its fill of blood, and their soil shall be gorged with fat. For the LORD has a day of vengeance, a year of recompense for the cause of Zion.
