Isaiah 34:5-8

5For my sword hath drunk its fill in heaven: behold, it shall come down upon Edom, and upon the people of my curse, to judgment. 6The sword of Jehovah is filled with blood, it is made fat with fatness, with the blood of lambs and goats, with the fat of the kidneys of rams; for Jehovah hath a sacrifice in Bozrah, and a great slaughter in the land of Edom. 7And the wild-oxen shall come down with them, and the bullocks with the bulls: and their land shall be drunken with blood, and their dust made fat with fatness.

8For Jehovah hath a day of vengeance, a year of recompense for the cause of Zion.
