2 Chronicles 7:6

6 The priests were standing at their posts. So were the Levites who had the LORD's musical instruments which King David made for praising the LORD with "his mercy endures forever" and which he used to offer praise. The priests were opposite the Levites blowing trumpets while all Israel was standing [there].

2 Chronicles 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.

2 Chronicles 7:6 In-Context

4 Then the king and all the people offered sacrifices to the LORD.

5 King Solomon offered 22,000 cattle and 120,000 sheep as sacrifices to the LORD. So the king and all the people dedicated God's temple.

6 The priests were standing at their posts. So were the Levites who had the LORD's musical instruments which King David made for praising the LORD with "his mercy endures forever" and which he used to offer praise. The priests were opposite the Levites blowing trumpets while all Israel was standing [there].

7 Solomon designated the courtyard in front of the LORD's temple as a holy place. He sacrificed the burnt offerings, grain offerings, and the fat because the bronze altar that he had made and that was in front of the LORD was not able to hold all of them.

8 At that time Solomon and all Israel celebrated the Festival [of Booths]. A very large crowd had come from [the territory between] the border of Hamath and the River of Egypt.
