"This is the service of the sons of Kohath in the Tent of Meeting, the most holy things.

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.

He appointed, according to the ordinance of David his father, the divisions of the priests to their service, and the Levites to their offices, to praise, and to minister before the priests, as the duty of every day required; the doorkeepers also by their divisions at every gate: for so had David the man of God commanded.

Hezekiah appointed the divisions of the priests and the Levites after their divisions, every man according to his service, both the priests and the Levites, for burnt offerings and for peace offerings, to minister, and to give thanks, and to praise in the gates of the camp of Yahweh.

So the service was prepared, and the priests stood in their place, and the Levites by their divisions, according to the king's commandment.
