And the priests stood in their offices: and the Levites with the instruments of music of the Lord, which king David made to praise the Lord: because his mercy endureth for ever, singing the hymns of David by their ministry: and the priests sounded with trumpets before them, and all Israel stood.
2 Chronicles 7:4 And the king and all the people sacrificed victims before the Lord.
2 Chronicles 7:5 And king Solomon offered a sacrifice of twenty-two thousand oxen, and one hundred and twenty thousand rams: and the king and all the people dedicated the house of God.
2 Chronicles 7:6 And the priests stood in their offices: and the Levites with the instruments of music of the Lord, which king David made to praise the Lord: because his mercy endureth for ever, singing the hymns of David by their ministry: and the priests sounded with trumpets before them, and all Israel stood.
2 Chronicles 7:7 Solomon also sanctified the middle of the court before the temple of the Lord: for he offered there the holocausts, and the fat of the peace offerings: because the brazen altar, which he had made, could not hold the holocausts and the sacrifices and the fat:
2 Chronicles 7:8 And Solomon kept the solemnity at that time seven days, and all Israel with him, a very great congregation, from the entrance of Emath to the torrent of Egypt.
The verse centers on "mercy", "priests", "stood", "offices", "levites", "instruments", "music", and "lord". It is saying that the verse draws attention to "mercy" and "priests", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 5's "And king Solomon offered a sacrifice of..." into verse 7's "Solomon also sanctified the middle of the...", so "mercy" and "priests" belong inside that flow. In 2 Chronicles context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "mercy" and "priests" with trust shaped by these words, not by a vague optimism outside the passage.
