14 Following the rules laid down by his father David, he organized the daily work of the priests and of the Levites who assisted the priests in singing hymns and in doing their work. He also organized the Temple guards in sections for performing their daily duties at each gate, in accordance with the commands of David, the man of God.

2 Chronicles 8:14 Meaning and Commentary

2 Chronicles 8:14

And he appointed, according to the order of David his father,
the courses of the priests to their service
The twenty four courses which served weekly in their turns, ( 1 Chronicles 24:1-31 )

and the Levites to their charges, to praise and minister before the
priests, as duty of every day required;
who also had their courses by lot, to sing the praises of God, when the priests sacrificed, or blew the trumpets, ( 1 Chronicles 25:1-31 ) ,

the porters also by their courses at every gate;
from hence Dr. Lightfoot concludes that these were divided into twenty four classes, as the priests and Levite singers were:

for so had David the man of God commanded,
( 1 Chronicles 26:1-32 ) , who in all these affairs acted as a prophet, under the inspiration and direction of the Holy Spirit of God.

12 Solomon offered sacrifices to the Lord on the altar which he had built in front of the Temple.
13 He offered burnt offerings according to the requirements of the Law of Moses for each holy day: Sabbaths, New Moon Festivals, and the three annual festivals - the Festival of Unleavened Bread, the Harvest Festival, and the Festival of Shelters.
14 Following the rules laid down by his father David, he organized the daily work of the priests and of the Levites who assisted the priests in singing hymns and in doing their work. He also organized the Temple guards in sections for performing their daily duties at each gate, in accordance with the commands of David, the man of God.
15 The instructions which David had given the priests and the Levites concerning the storehouses and other matters were carried out in detail.
16 By this time all of Solomon's projects had been completed. From the laying of the foundation of the Lord's Temple to its completion, all the work had been successful.
