2 Chronicles 8:14

14 According to the ordinance of David his father, he appointed the divisions of the priests for their service, and the Levites for their offices of praise and ministry before the priests as the duty of each day required, and the gatekeepers in their divisions for the several gates; for so David the man of God had commanded.

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 offered up burnt offerings to the LORD upon the altar of the LORD which he had built before the vestibule,

13 as the duty of each day required, offering according to the commandment of Moses for the sabbaths, the new moons, and the three annual feasts--the feast of unleavened bread, the feast of weeks, and the feast of tabernacles.

14 According to the ordinance of David his father, he appointed the divisions of the priests for their service, and the Levites for their offices of praise and ministry before the priests as the duty of each day required, and the gatekeepers in their divisions for the several gates; for so David the man of God had commanded.

15 And they did not turn aside from what the king had commanded the priests and Levites concerning any matter and concerning the treasuries.

16 Thus was accomplished all the work of Solomon from the day the foundation of the house of the LORD was laid until it was finished. So the house of the LORD was completed.
