2 Chronicles 8:14

14 And he ordained by the ordinance of David, his father, the offices of priests in their services, and the deacons in their order, that they should praise and minister before [the] priests by the custom of each day; and he ordained [the] porters in their partings by gate and gate. For David, the man of God, had commanded so; (And he ordained by the ordinance of his father David, the offices of the priests in their services, and the Levites in their order, to praise and to minister before the priests by the custom of each day; and he ordained the guards, or the doorkeepers, in their divisions by each gate. For David, the man of God, had so 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 sacrifices to the Lord on the altar of the Lord, which he had builded before the porch (which he had built in front of the vestibule),

13 that by all days offering should be offered in it, by the commandment of Moses, in sabbaths, and in calends, and in feast days, thrice by the year, that is, in the solemnity of therf loaves, and in the solemnity of weeks, and in the solemnity of tabernacles. (so that by all days the offerings would be offered on it, by the command of Moses, yea, on sabbaths, and calends, and Feast days, three times in the year, that is, on the Feast of Unleavened Bread, and the Feast of Weeks, and the Feast of Tabernacles.)

14 And he ordained by the ordinance of David, his father, the offices of priests in their services, and the deacons in their order, that they should praise and minister before [the] priests by the custom of each day; and he ordained [the] porters in their partings by gate and gate. For David, the man of God, had commanded so; (And he ordained by the ordinance of his father David, the offices of the priests in their services, and the Levites in their order, to praise and to minister before the priests by the custom of each day; and he ordained the guards, or the doorkeepers, in their divisions by each gate. For David, the man of God, had so commanded;)

15 and both priests and deacons passed not from the commandments of the king of all things which he had commanded. (and the priests and the Levites followed all the king's commands concerning everything which he commanded, including his orders about the treasuries.)

16 And Solomon had all [the] costs, or dispenses (or expenses), made ready in the keepings of [the] treasuries, from that day in which he founded the house of the Lord, till into the day in which he performed it. (And so Solomon founded the House of the Lord, and he finished it; and he successfully completed all of his work.)
