Daniel 8:19-21

And he said, Behold, I will make you know what will be in the latter time of the indignation [of God upon the ungodly], for it has to do with the time of the end. The ram you saw having two horns, they are the kings of Media and Persia. And the shaggy and rough he-goat is the king of Greece, and the great horn between his eyes is the first king [who consolidated the whole realm, Alexander the Great].
