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.
