'Two' in the Bible

Words of Amos -- who hath been among herdsmen of Tekoa -- that he hath seen concerning Israel, in the days of Uzziah king of Judah, and in the days of Jeroboam son of Joash king of Israel, two years before the shaking;

Do two walk together if they have not met?

Thus said Jehovah: As the shepherd delivereth from the lion's mouth Two legs, or a piece of an ear, So delivered are the sons of Israel, Who are sitting in Samaria on the corner of a bed, And in Damascus on that of a couch.

And wandered have two or three cities, Unto the same city to drink water, And they are not satisfied, And ye have not turned back unto Me, An affirmation of Jehovah.
