1 Chronicles 23:25-31

25For David said, “The Lord God of Israel 1has given rest to His people, and He dwells in Jerusalem forever.

26Also, 2the Levites will no longer need to carry the tabernacle and all its utensils for its service.”

27For by the last words of David, the sons of Levi were counted from twenty years old and upward.

28For their office is 3to assist the sons of Aaron with the service of the house of the Lord, in the courtyards and in the chambers, and in the purification of all holy things, and the work of the service of the house of God,

294and with the showbread, and 5the fine flour for a grain offering, and unleavened wafers, or 6what is baked in the pan or 7what is well-mixed, and 8all measures of volume and size.

30They are to stand every morning to thank and to praise the Lord, and likewise at evening,

31and to offer all burnt offerings to the Lord, 9on the Sabbaths, the new moons and 10the appointed festivals, in the number determined by the ordinance concerning them, continually before the Lord.
