I Chronicles 23:1

So when David was old and full of days,.... Perhaps was now in the last year of his age, about seventy years old, though before he was bedridden; see Ch1 28:2, he made Solomon his son king over Israel; declared him to be his successor; this was before the affair of Adonijah, for then he ordered him to be anointed king, and placed on the throne; and this aggravated the rebellion of Adonijah, that it was against the declared and known will of his father.

Here we have, I. The crown entailed, according to the divine appointment, Ch1 23:1. David made Solomon king, not to reign with him, or reign under him, but only to reign after him. This he did, 1. When he was old and full of days. He was but seventy years old when he died, and yet he was full of days, satur dierum - satisfied with living in this world. When he found himself going off, he made provision for the welfare of the kingdom after his decease, and pleased himself with the hopeful prospect of a happy settlement both in church and state. 2.

Note, The settling or securing of the crown in the interests of the temple is a great blessing to the people and a great satisfaction to those who are themselves leaving the world. II. The Levites numbered, according to the rule in Moses's time, from thirty years old to fifty, Num 4:2, Num 4:3. Their number in Moses's time. by this rule, was 8580 (Num 4:47, Num 4:48), but now it had increased above four-fold, much more in proportion than the rest of the tribes; for the serviceable men of Levi's tribe were now 38,000, unless we suppose that here those were reckoned who were above fifty, which was not the case there. Joab had not numbered the Levites (Ch1 21:6), but David now did, not in pride, but for a good purpose, and then he needed not fear wrath for it. III. The Levites distributed to their respective posts (Ch1 23:4, Ch1 23:5), that every hand might be employed (for, of all men, an idle Levite makes the worst figure), and that every part of the work might be car…

23:1-2 When David . . . appointed his son Solomon as Israel’s king (cp. 1 Kgs 1), David outlined the organizational structure of the kingdom and made all the necessary provisions for the Temple’s functioning. • The account of Solomon’s coronation continues in 1 Chr 28–29; the intervening chapters (23:3–27:24) record in detail the organization of the kingdom.
