As I was considering, behold, a he-goat [the king of Greece] came from the west across the face of the whole earth without touching the ground, and the goat had a conspicuous and remarkable horn between his eyes [symbolizing Alexander the Great]. [Dan. 8:21.] (AMP)
And as I was considering, behold, an he goat came from the west on the face of the whole earth, and touched not the ground: and the goat had a notable horn between his eyes. (KJV)
