Ezekiel's imagination, never weary of contemplating the destruction of those alien hordes, now pictures them as a sacrifice, to devour which Yahweh invites the birds and beasts, who gorge themselves with their flesh and blood.
Ezekiel 39:17-20
17 And, thou son of man, thus saith the Lord GOD; Speak unto every feathered fowl, and to every beast of the field, Assemble yourselves, and come; gather yourselves on every side to my sacrifice that I do sacrifice for you, even a great sacrifice upon the mountains of Israel, that ye may eat flesh, and drink blood.
18 Ye shall eat the flesh of the mighty, and drink the blood of the princes of the earth, of rams, of lambs, and of goats,h of bullocks, all of them fatlings of Bashan.
19 And ye shall eat fat till ye be full, and drink blood till ye be drunken, of my sacrifice which I have sacrificed for you.
20 Thus ye shall be filled at my table with horses and chariots, with mighty men, and with all men of war, saith the Lord GOD.
