Daniel Chapter 8 Vs. 6

 Daniel's Vision of the Ram and the Goat

Daniel 8:6 "And he came to the ram that had [two] horns, which I had seen standing before the river, and ran unto him in the fury of his power."

This is explaining that Alexander the great fought against the Medes and the Persians.

The goat, determined to destroy the two-horned ram, went at him in great rage… furiously and broke the ram’s two horns.
