In Ezekiel 39, who did God invite to eat flesh and get drunk with blood?

The birds and beasts

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. ...

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.

Thus ye shall be filled at my table. Ezekiel 39:17-20
