Daniel 8:19-21

He said, “Behold, I am going to let you know what will happen during the final time of the indignation and wrath [of God upon the ungodly], for it concerns the appointed time of the end. The ram which you saw with the two horns represents the kings of Media and Persia. The shaggy (rough-coated) male goat represents the kingdom of Greece, and the great horn between his eyes is the first king.
