Daniel 8:7, 27

[In my vision] I saw him come close to the ram (Medo-Persia), and he was filled with rage toward him; and the goat (Greece) struck the ram and shattered his two horns, and the ram had no strength to stand before him. So the goat threw him to the ground and trampled on him, and there was no one who could rescue the ram from his power.

And I, Daniel, was exhausted and was sick for [several] days. Afterward I got up and continued with the king’s business; but I was astounded at the vision, and there was no one who could explain it.
