Chronicles II 7:6

6 And the priests were standing at their watches, and the Levites with instruments of music of the Lord, belonging to king David, to give thanks before the Lord, for his mercy for ever, with the hymns of David, by their ministry: and the priests were blowing the trumpets before them, and all Israel standing.

Chronicles II 7:6 Meaning and Commentary

2 Chronicles 7:6

And the priests waited on their offices
Performed them, some in offering sacrifices, others in blowing trumpets, as it may be explained from the latter part of the verse:

the Levites also with instruments of music of the Lord, which David the
king had made to praise the Lord;
under a divine direction, on which the Levites played to the songs of praise offered to the Lord, and by which they made music sacred to him:

because his mercy endureth for ever;
which, as it was the close of their songs of praise, was the cause of them:

when David praised by their ministry;
the songs sung being composed by him, and the instruments they played upon being of his invention, and used by his order:

and the priests sounded trumpets before them;
or rather over against them, that is, over against the Levites, as they were singing and playing on the instruments of music:

and all Israel stood;
while this sacred and delightful service was performing, they both stood up, and stood by the priests and Levites, and joined with them in praising the Lord.

Chronicles II 7:6 In-Context

4 And the king and all the people offering sacrifices before the Lord.

5 And king Solomon offered a sacrifice of calves twenty and two thousand, of sheep a hundred and twenty thousand: so the king and all the people dedicated the house of God.

6 And the priests were standing at their watches, and the Levites with instruments of music of the Lord, belonging to king David, to give thanks before the Lord, for his mercy for ever, with the hymns of David, by their ministry: and the priests were blowing the trumpets before them, and all Israel standing.

7 And Solomon consecrated the middle of the court that was in the house of the Lord: for he offered there the whole-burnt-offerings and the fat of the peace-offerings, for the brazen altar which Solomon had made was not sufficient to receive the whole-burnt-offerings, and the meat-offerings, and the fat.

8 And Solomon kept the feast at that time seven days, and all Israel with him, a very great assembly, from the entering in of Aemath, and as far as the river of Egypt.
