Ye shall - drink the blood of the princes of the earth - I need not mention the custom of the Scandinavians: they were accustomed to drink the blood of their enemies out of the skulls of the dead. But this is spoken of fowls and beasts here - rams, lambs, and goats. The feast shall be as grateful and as plenteous to the fowls and beasts, as one made of the above animals, the fattest and best of their kind, (because fed in the fertile fields of Bashan), would be to the guests of him who makes a sacrifice.
The purposes of the past dispensation shall be made clear to God‘s people themselves and to the pagan. His judgments were the consequence of their sins; and these sins once abandoned, the favor of their God will return in yet more abundance.
Ezekiel 39:29
Compare Acts 2:17. Peter distinctly appropriates these prophecies (marginal references) to the outpouring of the Holy Spirit on the day of Pentecost, and the inauguration of the Church of Christ by that miraculous event. This was the beginning of the fulfillment. They shall find their consummation when time shall be no more.
