There, before the ark, King Solomon and the whole congregation of Israel who had assembled with him sacrificed so many sheep and oxen that they could not be counted or numbered.

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.
