'Divisions' in the Bible

These are the people of the divisions of the kingdom, among those who had been made prisoners by Nebuchadnezzar, the king of Babylon, and taken away by him, who went back to Jerusalem and Judah, every one to his town;

Now these are the chiefs of the divisions of the country who were living in Jerusalem: but in the towns of Judah everyone was living on his heritage in the towns, that is, Israel, the priests, the Levites, the Nethinim, and the children of Solomon's servants.

And of the Levites, certain divisions in Judah were joined to Benjamin.
