'Two' in the Bible

The words of Amos, who was among the herdsmen of Tekoa; what he saw about 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 earth-shock.

These are the words of the Lord: For three crimes of Israel, and for four, I will not let its fate be changed; because they have given the upright man for silver, and the poor for the price of two shoes;

Is it possible for two to go walking together, if not by agreement?

These are the words of the Lord: As the keeper of sheep takes out of the mouth of the lion two legs or part of an ear; so will the children of Israel be made safe, who are resting in Samaria on seats of honour or on the silk cushions of a bed.

So two or three towns went wandering to one town looking for water, and did not get enough: and still you have not come back to me, says the Lord.

Getting the poor for silver, and him who is in need for the price of two shoes, and taking a price for the waste parts of the grain.
