"Then lifted I up mine eyes, and saw, and behold four horns. (19) And I said unto the angel that talked with me, What be these? And he answered me, These are the horns which have scattered Judah, Israel, and Jerusalem."
Probably (but I do not determine) by these four horns as they are said to have scattered, Judah, Israel, and Jerusalem, may be meant those four kingdoms which did indeed sadly afflict the Lord's Church; that is the Chaldean, the Persian, the Grecian, and the Roman; thus extending to the time of Christ's coming.
