'Two' in the Bible

I looked up, and there was a ram standing beside the canal. He had two horns. The two horns were long, but one was longer than the other, and the longer one came up last.

He came toward the two-horned ram I had seen standing beside the canal and rushed at him with savage fury.

I saw him approaching the ram, and infuriated with him, he struck the ram, shattering his two horns, and the ram was not strong enough to stand against him. The goat threw him to the ground and trampled him, and there was no one to rescue the ram from his power.

The two-horned ram that you saw represents the kings of Media and Persia.

The two kings, whose hearts are bent on evil, will speak lies at the same table but to no avail, for still the end will come at the appointed time.

Then I, Daniel, looked, and two others were standing there, one on this bank of the river and one on the other.
