2 Chronicles 7:6
And the priests waited on their offices: the Levites also with instruments of musick of the LORD, which David the king had made to praise the LORD, because his mercy endureth for ever, when David praised by their ministry; and the priests sounded trumpets before them, and all Israel stood.
2 Chronicles 7:6 belongs to the account of Solomon's reign over the undivided kingdom, presented as his reign in Judah.
Within that reign it belongs to the section that recounts the temple's building and furnishings, its services, its dedication prayer and sacrifices, God's answer to Solomon's prayer, and the order of events at the dedication.
The book presents this material as religious history emphasizing God's care for his people and his purpose to save them, where divine favor depends on faithfulness to the covenant and punishment follows unfaithfulness.
At the temple dedication Solomon takes the leading role, while the priests are mentioned only as bearers of the ark and the high priest is not mentioned.
