Then the priests brought the ark of the covenant of the LORD to its place in the inner sanctuary of the temple, the Most Holy Place, beneath the wings of the cherubim.
This agrees with what we had Kg1 8:2, etc., where an account was given of the solemn introduction of the ark into the new-erected temple. 1. There needed no great solemnity for the bringing in of the dedicated things, Ch2 5:1.

2Ch 5:4-9 Instead of הלויּם, we have in 2 Kings הכּהנים, the priests bare the ark; and since even according to the Chronicle (2Ch 5:7) the priests bare the ark into the holy place, we must understand by הלויּם such Levites were also priests. - In 2Ch 5:5, too the words הלויּם הכּהנים are inexact, and are to be corrected by 1Ki 8:4, והלויּם הכּהנים.
