(10) “Shemaiah . . . wrote” (1Ch 24:6) (about David), and the words of Shemaiah the prophet and of Iddo the visionary by genealogical enrollment (2Ch 12:15) (about Rehoboam) (perhaps two or three sources)

He has given us many details that bear on true worship: the bringing of the Ark to Jerusalem by David (1Ch chaps 15, 16); David’s preparations for the temple and its service (1Ch chaps 22–29); the fact that the priests stayed with Rehoboam at the time of the secession of the ten tribes (2Ch 11:13-17); the war between Abijah and Jeroboam (2Ch 13); the reforms in favor of true religion under Asa (2Ch chaps 14, 15), Jehoshaphat (2Ch chaps 17, 19, 20), Hezekiah (2Ch chaps 29–31), and Josiah (2Ch chaps 34, 35); Uzziah’s being stricken with leprosy for his presumptuousness (2Ch 26:16-21); and Manasseh’s repentance (2Ch 33:10-20).

First Chronicles chapters 23 to 27 shows the numerous and varied positions and arrangements for oversight in effect during David’s reign, as regards both the priesthood and the royal court, including economic and military matters.

David also provided the architectural plans, received by inspiration, and organized the tens of thousands of Levites into their many divisions of service, including a great chorus of singers and musicians.​—1Ch 23:1–29:19; 2Ch 8:14; 23:18; 29:25; Ezr 3:10.

The service of the Levites at the sanctuary began at age 25 (reduced in King David’s time to 20). (Nu 8:24; 1Ch 23:24)

Of the 24 divisions, or courses, of the priests established by King David, 16 were made up from the house of Eleazar and 8 from the house of Ithamar. (1Ch 24:1-19)

At times the term applies to the whole tribe, but usually it excludes the priestly family of Aaron (Jos 14:3, 4; 21:1-3); thus the expression “priests and Levites” is common. (1Ki 8:4; 1Ch 23:2; Ezr 1:5; Joh 1:19)

The Levites were made up of three families, from Levi’s sons Gershon (Gershom), Kohath, and Merari. (Ge 46:11; 1Ch 6:1, 16)

Later, they served likewise at the temple. (1Ch 23)
