Albert Barnes Commentary Daniel 8:3

"Then I lifted up mine eyes, and saw, and, behold, there stood before the river a ram which had two horns: and the two horns were high; but one was higher than the other, and the higher came up last." — Daniel 8:3 (ASV)

Then I lifted up my eyes and saw - And saw in vision, or there seemed to be before me.

There stood before the river - On the bank of the river.

A ram which had two horns - There can be no error in explaining the design of this symbol, for in (Daniel 8:20) it is expressly said that it denoted the two kings of Media and Persia. The united power of the kingdom was denoted by the ram itself; the fact that there were two powers or kingdoms combined, by the two horns of the ram.

And the two horns were high - Both indicating great power.

But one was higher than the other, and the higher came up last - The higher horn springing up last denotes Persia, which became the more powerful of the two, so that the name Media was finally almost dropped, and the united kingdom was known in Greek history as the Persian. The Median or Assyrian power was the older, but the Persian became the most powerful.
