Isaya 34 : 6 Isaiah chapter 34 verse 6

Upanga wa Bwana umeshiba damu, umenona kwa unono, kwa damu ya wana-kondoo na mbuzi, kwa mafuta ya figo za kondoo waume; maana Bwana ana dhabihu huko Bozra, machinjo makubwa katika nchi ya Edomu.

The sword of Yahweh is filled with blood, it is made fat with fatness, 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.
