Isaiah 34:5-8

5And when my sword has finished its work in the heavens, it will fall upon Edom, the nation I have marked for destruction.

6The sword of the Lord is drenched with blood and covered with fat— with the blood of lambs and goats, with the fat of rams prepared for sacrifice. Yes, the Lord will offer a sacrifice in the city of Bozrah. He will make a mighty slaughter in Edom.

7Even men as strong as wild oxen will die— the young men alongside the veterans. The land will be soaked with blood and the soil enriched with fat.

8For it is the day of the Lord’s revenge, the year when Edom will be paid back for all it did to Israel.
