Isaiah 34:5-6

NHEB(i) 5 For my sword has drunk its fill in the sky. Look, it will come down on Edom, and on the people of my curse, for judgment. 6 The LORD's sword is filled with blood. It is covered 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, And a great slaughter in the land of Edom.
