Isaiah 34:5-7 NIV

5 My sword has drunk its fill in the heavens; see, it descends in judgment on Edom, the people I have totally destroyed.
6 The sword of the LORD is bathed in blood, it is covered with fat— the blood of lambs and goats, fat from the kidneys of rams. For the LORD has a sacrifice in Bozrah and a great slaughter in the land of Edom.
