'Grouped' in the Bible

And Jehoiada put the work and the care of the house of the Lord into the hands of the priests and the Levites, who had been grouped in divisions by David to make burned offerings to the Lord, as it is recorded in the law of Moses, with joy and song as David had said.

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.
