'Two' in the Bible

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

Do two walk together unless they have met?

Thus says Yahweh, "Just as the shepherd rescues two legs or a piece of an ear from the mouth of the lion, so shall the {people} of Israel who dwell in Samaria, with the corner of a couch and the damask of a bed."

So two [or] three cities wandered to one city to drink water and they were not satisfied, yet you did not return to me," [is] the declaration of Yahweh.
