Esias 34:5

5 My sword has been made drunk in heaven: behold, it shall come down upon Idumea, and with judgment upon the people doomed to destruction.

Esias 34:5 In-Context

3 And their slain shall be cast forth, and their corpses; and their savour shall come up, and the mountains shall be made wet with their blood.
4 And all the powers of the heavens shall melt, and the sky shall be rolled up like a scroll: and all the stars shall fall like leaves from a vine, and as leaves fall from a fig-tree.
5 My sword has been made drunk in heaven: behold, it shall come down upon Idumea, and with judgment upon the people doomed to destruction.
6 The sword of the Lord is filled with blood, it is glutted with fat, with the blood of goats and lambs, and with the fat of goats and rams: for the Lord has a sacrifice in Bosor, and a great slaughter in Idumea.
7 And the mighty ones shall fall with them, and the rams and the bulls; and the land shall be soaked with blood, and shall be filled with their fat.
