The sword of the LORD is filled with blood, it is made fat with fatness, [and] with the blood of lambs and goats, with the fat of the kidneys of rams: for the LORD hath a sacrifice in Bozrah, and a great slaughter in the land of Idumea.
Berean Study Bible (BSB) - Isaiah 34:6 >The sword of the LORD is bathed in 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.
