2. he gathered together all the princes of Israel—All important measures relating to the public interest were submitted for consideration to a general assembly of the representatives of the tribes (1Ch 13:1; 15:25; 22:17; 26:1-32).

     3. the Levites were numbered . . . thirty and eight thousand—Four times their number at the early census taken by Moses (see on Nu 4:1-49; 26:1-51). It was, in all likelihood, this vast increase that suggested and rendered expedient that classification, made in the last year of David's reign, which the present and three subsequent chapters describe.

     4. twenty and four thousand were to set forward the work of the house of the Lord—They were not to preside over all the services of the temple. The Levites were subject to the priests, and they were superior to the Nethinim and other servants, who were not of the race of Levi. But they had certain departments of duty assigned, some of which are here specified.

     5. praised the Lord with the instruments which I made—David seems to have been an inventor of many of the musical instruments used in the temple (Am 6:5).

     6. David divided them into courses among the sons of Levi—These are enumerated according to their fathers' houses, but no more of these are mentioned here than the twenty-four thousand who were engaged in the work connected with the Lord's house. The fathers' houses of those Levites corresponded with the classes into which they [JOSEPHUS, Antiquities] as well as the priests were divided (see on 1Ch 24:20-31; 1Ch 26:20-28).
