Isaiah 34:6
Amplified Bible (AMP)
The sword of the Lord is filled with blood [of sacrifices], it is gorged and greased with fatness--with the blood of lambs and goats, with the fat of the kidneys of rams. For the Lord has a sacrifice in Bozrah [capital of Edom] and a great slaughter in the land of Edom.— Isaiah 34:6 (AMP)
