'Divisions' in the Bible

David divided them into divisions according to the sons of Levi: Gershon, Kohath, and Merari.

These were the divisions of the sons of Aaron. The sons of Aaron: Nadab and Abihu, Eleazar and Ithamar.

For the divisions of the doorkeepers: of the Korahites, Meshelemiah the son of Kore, of the sons of Asaph.

Of these were the divisions of the doorkeepers, even of the chief men, having offices like their brothers, to minister in the house of Yahweh.

These were the divisions of the doorkeepers; of the sons of the Korahites, and of the sons of Merari.

Now the children of Israel after their number, the heads of fathers' [houses] and the captains of thousands and of hundreds, and their officers who served the king, in any matter of the divisions which came in and went out month by month throughout all the months of the year -- of every division were twenty-four thousand.

also for the divisions of the priests and the Levites, and for all the work of the service of the house of Yahweh, and for all the vessels of service in the house of Yahweh;

Behold, there are the divisions of the priests and the Levites, for all the service of the house of God. There shall be with you in all kinds of work every willing man who has skill, for any kind of service. Also the captains and all the people will be entirely at your command."
