Isaiah 34:5-6

34:5 He says, “Indeed, my sword has slaughtered heavenly powers.

Look, it now descends on Edom,

on the people I will annihilate in judgment.”

34:6 The Lord’s sword is dripping with blood,

it is covered with fat;

it drips with the blood of young rams and goats

and is covered with the fat of rams’ kidneys.

For the Lord is holding a sacrifice in Bozrah,

a bloody slaughter in the land of Edom.
