They are to carry out their responsibilities for the tent of meeting, for the holy place, and for their relatives, the sons of Aaron, in the service of the Lord’s temple.”
They also appointed the priests by their divisions and the Levites by their groups to the service of God in Jerusalem, according to what is written in the book of Moses.
