Isaiah 34:6

The sword of the Lord is filled with blood, glutted with heavy slaughter; it is made fat with fatness, as it engages in bringing sacrifice, and with the blood of lambs and goats, with the fat of the kidneys of rams, those parts being named which were especially devoted to God in the sacrifices, 2 Samuel 1:22; for the Lord hath a sacrifice in Bozrah, the capital of Auranitis, east of Jordan, for thus far Edom had extended its dominion at that time, and a great slaughter in the land of Idumea, whose territory extended from the southern end of the Dead Sea to the Elanitic Gulf.
