and they brought up the ark and the Tent of Meeting with all its sacred furnishings. The Levitical priests carried them up.
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.
