2 Chronicles 8:14

14 In assigning the priests to their duties, Solomon followed the regulations of his father, David. He also assigned the Levites to lead the people in praise and to assist the priests in their daily duties. And he assigned the gatekeepers to their gates by their divisions, following 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.

2 Chronicles 8:14 In-Context

12 Then Solomon presented burnt offerings to the LORD on the altar he had built for him in front of the entry room of the Temple.

13 He offered the sacrifices for the Sabbaths, the new moon festivals, and the three annual festivals—the Passover celebration, the Festival of Harvest, and the Festival of Shelters—as Moses had commanded.

14 In assigning the priests to their duties, Solomon followed the regulations of his father, David. He also assigned the Levites to lead the people in praise and to assist the priests in their daily duties. And he assigned the gatekeepers to their gates by their divisions, following the commands of David, the man of God.

15 Solomon did not deviate in any way from David’s commands concerning the priests and Levites and the treasuries.

16 So Solomon made sure that all the work related to building the Temple of the LORD was carried out, from the day its foundation was laid to the day of its completion.
