Isaiah 34:5-8

5When my sword has drunk its fill in the heavens, it will then come down on Edom and on the people I have set apart for destruction.

6The Lord’s sword is covered with blood. It drips 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.

7The wild oxen will be struck down with them, and young bulls with the mighty bulls. Their land will be soaked with blood, and their soil will be saturated with fat.

8For the Lord has a day of vengeance, a time of paying back Edom for its hostility against Zion.
