The same Edom/Bozrah judgment scene, there described directly - here pictured through the returning warrior's own bloodied clothing.
Who is this who comes from Edom, with dyed garments from Bozrah? Who this who is glorious in his clothing, marching in the greatness of his strength? “It is I who speak in righteousness, mighty to save.”
Yahweh’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 Yahweh has a sacrifice in Bozrah, And a great slaughter in the land of Edom.
This chapter turns from Zion's own glorification to a sobering scene of judgment before opening into a long communal prayer confessing Israel's own failure.
