Isaiah 34:5-7 NIV

5 My sword1 has drunk its fill in the heavens; see, it descends in judgment on Edom,2 the people I have totally destroyed.3
6 The sword4 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 sacrifice5 in Bozrah6 and a great slaughter7 in Edom.
