Daniel 8:5-8

8:5 While I was contemplating all this, a male goat was coming from the west over the surface of all the land without touching the ground. This goat had a conspicuous horn between its eyes. 8:6 It came to the two-horned ram that I had seen standing beside the canal and rushed against it with raging strength. 8:7 I saw it approaching the ram. It went into a fit of rage against the ram and struck it and broke off its two horns. The ram had no ability to resist it. The goat hurled the ram to the ground and trampled it. No one could deliver the ram from its power. 8:8 The male goat acted even more arrogantly. But no sooner had the large horn become strong than it was broken, and there arose four conspicuous horns in its place, extending toward the four winds of the sky.

Daniel 8:21

8:21 The male goat is the king of Greece, and the large horn between its eyes is the first king.
