2 Chronicles 8:14

14 And, according to the order of David his father, he appointed the divisions of the priests for their service, the Levites for their duties (to praise and serve before the priests) as the duty of each day required, and the gatekeepers by their divisions at each gate; 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 burnt offerings to the Lord on the altar of the Lord which he had built before the vestibule,

13 according to the daily rate, offering according to the commandment of Moses, for the Sabbaths, the New Moons, and the three appointed yearly feasts--the Feast of Unleavened Bread, the Feast of Weeks, and the Feast of Tabernacles.

14 And, according to the order of David his father, he appointed the divisions of the priests for their service, the Levites for their duties (to praise and serve before the priests) as the duty of each day required, and the gatekeepers by their divisions at each gate; for so David the man of God had commanded.

15 They did not depart from the command of the king to the priests and Levites concerning any matter or concerning the treasuries.

16 Now all the work of Solomon was well-ordered from the day of the foundation of the house of the Lord until it was finished. So the house of the Lord was completed.
