6 The priests stood, according to their positions; the Levites also with instruments of music of Yahweh, which David the king had made to give thanks to Yahweh, when David praised by their ministry, saying "For his loving kindness endures for ever." The priests sounded trumpets before them; and all Israel stood.

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.
David praised - For David composed the psalms or hymns, and appointed them to be sung by the Levites, and instrumental music to be joined to their voices.
