1 Chronicles 23:24-32

24These were the sons of Levi according to their fathers' houses, the chief fathers, as they were reckoned, by number of names by their polls, who did the work of the service of the house of Jehovah, from twenty years old and upward. 25For David said, Jehovah the 1God of Israel has given rest to his people, and he will dwell in Jerusalem for ever; 26and the Levites also have no more to carry the tabernacle, nor any of its vessels for its service. 27For by the last words of David was this [done], — the numbering of the sons of Levi from twenty years old and upward. 28For their place was by the side of the sons of Aaron for the service of the house of Jehovah, over the courts, and over the chambers, and over the purifying of all holy things, and [for] the work of the service of the house of 2God; 29and for the loaves to be set in rows, and for the fine flour for the oblation, and for the unleavened cakes, and for [what is baked in] the pan, and for that which is saturated [with oil], and for all measure of capacity and size; 30and to stand every morning to thank and praise Jehovah, and likewise at even; 31and for all burnt-offerings offered up to Jehovah on the sabbaths, on the new moons, and on the set feasts, by number, according to the ordinance concerning them, continually, before Jehovah; 32and they kept the charge of the tent of meeting, and the charge of the sanctuary, and the charge of the sons of Aaron their brethren, in the service of the house of Jehovah.
