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 unto the LORD on the altar of the LORD, which he had built before the porch,

13 according to a certain rate every day, offering according to the commandment of Moses on the Sabbaths and on the new moons and on the solemn feasts, three times in the year: on the Feast of Unleavened Bread and on the Feast of Weeks and on the Feast of Tabernacles.

14 And he appointed, according to the order of David his father, the courses of the priests for their service, and the Levites to their charges to praise and minister before the priests, as the duty of every day required; the gatekeepers also by their courses at every gate, for so had David the man of God commanded.

15 And they departed not from the commandment of the king unto the priests and Levites concerning any matter or concerning the treasurers.

16 Now all the work of Solomon was prepared unto the day of the foundation of the house of the LORD and until it was finished. So the house of the LORD was perfected.
