“And you will eat fat until you are full, and drink blood until you are drunk, of my sacrifice which I have sacrificed for you.”
Nothing could have been designed to make Ezekiel shudder more. The eating of the fat and the drinking of the blood of sacrifices were forbidden to men. And here it is the blood of men. But here it is the wild beasts who partake. It stresses the awfulness of the fate of these people. And the beasts will be more than sated.
