1 Chronicles 23:24-32 - The Levites' Work
24 These were the descendants of Levi according to their ancestral households, with family heads documented according to the names of persons 20 years and older who were appointed to perform work in service to the Temple of the LORD. 25 For David had said "The LORD God of Israel has granted rest to his people, and he has taken Israel as his eternal residence. 26 Therefore the descendants of Levi are no longer to carry the Tent or its service implements." 27 Since, according to David's final instructions, the list above contains the total number of descendants of Levi from the age of 20 years and upward, 28 David issued these orders: 29 "Instead, they are to assist by lending a hand to the descendants of Aaron regarding service to the Temple of the LORD relating to the courts, the chambers, purification of everything pertaining to holiness, and to anything else pertaining to service on behalf of the Temple of God, including assisting with the rows of showbread, selecting flour for the grain offerings, the unleavened bread, baked offerings, and oil-based offerings, no matter what the quantity or sizes. 30 They are to take their stand morning by morning, thanking and praising the LORD right through until the evening, 31 whenever burnt offerings are presented to the LORD, whether on Sabbaths, New Moons, or scheduled festivals, regularly in the LORD's presence in accordance with the number required to conduct their service. 32 By doing this, they will fulfill their obligation as trustees over the Tent of Assembly and the Sanctuary, attending to the needs of their relatives, who are descendants of Aaron, in keeping with their service on behalf of the Temple of the LORD."
