'Divisions' in the Bible

And when the priests came out of the sanctuary (for all the priests who were present sanctified themselves without keeping their divisions)

And Uzziah had troops {trained and ready for war} in divisions according to the number of their enrollment at the hand of Jeuel the scribe and Maaseiah the officer, under the hand of Hananiah of the king's commanders.

And Hezekiah appointed working groups of the priests and the Levites, each according to their divisions, {according to the service for priests and Levites}, for burnt offerings, for peace offerings, to serve, to give thanks, and to praise in the gates of the camps of Yahweh.
