So the priests and the Levites consecrated themselves to bring up the ark of the LORD, the God of Israel.
Preparation is here made for the bringing of the ark home to the city of David from the house of Obed-edom. It is here owned that in the former attempt, though it was a very good work and in it they sought God, yet they sought him, not after the due order, Ch1 15:13.

So the priests and the Levites sanctified themselves,.... As they were ordered, and in the manner they should: to bring up the ark of the Lord God of Israel; for though it was chiefly the work of the Levites, yet the priests might do it, and sometimes did, see Jos 3:13.
1Ch 15:14-15 The Levites consecrated themselves, and bare - as 1Ch 15:15 anticipatively remarks-the ark of God upon their shoulders, according to the prescription in Num 7:9, עליהם בּמּומות, by means of poles upon them (the shoulders). מוטה, the flexible pole used for carrying burdens, Num 13:23. Those used to carry the ark are called בּדּים in the Pentateuch, Exo 25:13.
