'Division' in the Bible

Then Hezekiah put in order the divisions of the priests and Levites, every man in his division, in relation to his work, for the burned offerings and peace-offerings, and for the ordering of worship and for giving praise at the doors of the Lord's house.

And take your positions in the holy place, grouped in the families of your brothers, the children of the people, and for every division let there be a part of a family of the Levites.
