Isaiah 34:6-8

CLV(i) 6 The sword of Yahweh will be full of blood. It lubricates itself from the fat of lambs, and from the blood of butting rams and he-goats, from the fat of kidneys of rams. For there shall be a sacrifice to Yahweh in Bozrah, and a great slaughter in the land of Edom." 7 And down come the uruses with them, and the young bulls with the bulls, and their land will be soaked with blood, and their soil shall be sleek from fat." 8 For a day of vengeance is it for Yahweh, a year of repayments for the contention of Zion."
