Isaiah 34:5 In-Context

3 And their slain shall be cast out, and their stink shall come up from their carcases, and the mountains shall be melted with their blood.
4 And all the host of the heavens shall be dissolved, and the heavens shall be rolled together as a scroll; and all their host shall fade away, as a leaf fadeth from off the vine, and as the withered [fruit] from the fig-tree.
5 For my sword is bathed in the heavens; behold, it shall come down upon Edom, and upon the people of my ban, to judgment.
6 The sword of Jehovah 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 Jehovah hath a sacrifice in Bozrah, and a great slaughter in the land of Edom.
7 And the buffaloes shall come down with them, and the bullocks with the bulls; and their land shall be soaked with blood, and their dust made fat with fatness.
