Daniel 8:3-4

Then I raised my eyes and looked, and behold, there in front of the canal stood a [lone] ram (the Medo-Persian Empire) which had two horns. The two horns were high, but one (Persia) was higher than the other (Media), and the higher one came up last. I saw the ram (Medo-Persia) charging westward and northward and southward; no beast could stand before him, nor was there anyone who could rescue [anything] from his power, but he did as he pleased and magnified himself. [Dan 8:20]
