'Goat' in the Bible

As I was observing [this], behold, a male goat (Greece) was coming from the west [rushing] across the face of the whole earth without touching the ground; and the goat had a conspicuous and remarkable horn (Alexander the Great) between his eyes.

[In my vision] I saw him come close to the ram (Medo-Persia), and he was filled with rage toward him; and the goat (Greece) struck the ram and shattered his two horns, and the ram had no strength to stand before him. So the goat threw him to the ground and trampled on him, and there was no one who could rescue the ram from his power.
