Daniel 8:16-20

And I heard a man’s voice between the banks of Ulai, which called, and said, Gabriel, make this man to understand the vision.

So he came near where I stood: and when he came, I was afraid, and fell upon my face: but he said unto me, Understand, O son of man: for at the time of the end shall be the vision.

Now as he was speaking with me, I was in a deep sleep on my face toward the ground: but he touched me, and set me upright.

And he said, Behold, I will make thee know what shall be in the last end of the indignation: for at the time appointed the end shall be.

The ram which thou sawest having two horns are the kings of Media and Persia.
