Chapter 8 zooms in on two of the four empires from last week — Persia and Greece — and describes events still two centuries in the future when Daniel wrote them. A ram charges in every direction, unstoppable. Then a goat appears from the west moving so fast it doesn't touch the ground. It destroys the ram and becomes the dominant power in the world. Then at the absolute peak of its strength, its great horn snaps.
The goat is Greece. The great horn is Alexander the Great — who conquered from Macedonia to India in under a decade, died at 32 with no heir, and whose empire immediately fractured into four kingdoms. Each detail matches. Written two centuries before Alexander was born.
From one of those four kingdoms rises a little horn — a king who targets Israel, shuts down the temple sacrifices, and defiles the sanctuary. This was fulfilled in 167 BC by a king named Antiochus Epiphanes, who erected a pagan altar in the Jerusalem temple and sacrificed a pig on it. The Maccabees revolted, the temple was rededicated three years later — that's Hanukkah.
But the angel Gabriel — appearing here for the first time in the Bible — tells Daniel three times that the vision extends beyond Antiochus to the time of the end. Antiochus is a preview. The near fulfillment points to a far horizon that history hasn't reached yet.
Daniel is so overwhelmed he lies sick for days. When he gets up he returns to the king's business — appalled and not fully understanding. He goes back to ordinary work carrying something too large to explain. That's a posture worth admiring.
