'Two' in the Bible

The words of Amos, who was among the herdmen of Tekoa, which he saw concerning Israel in the days of Uzziah king of Judah, and in the days of Jeroboam the son of Joash, king of Israel, two years before the earthquake.

Shall two walk together except they be agreed?

Thus saith Jehovah: Like as the shepherd rescueth out of the jaw of the lion two legs, or a piece of an ear; so shall the children of Israel be rescued that sit in Samaria in the corner of a couch, and upon the damask of a bed.

And two, three, cities wandered unto one city, to drink water, and were not satisfied: yet have ye not returned unto me, saith Jehovah.
