1 Chronicles 15:12-16

12He said to them, “You are the heads of the Levitical families; you and your fellow Levites are to consecrate yourselves and bring up the ark of the LORD, the God of Israel, to the place I have prepared for it. 13It was because you, the Levites, did not bring it up the first time that the LORD our God broke out in anger against us. We did not inquire of him about how to do it in the prescribed way.” 14So the priests and Levites consecrated themselves in order to bring up the ark of the LORD, the God of Israel.

15And the Levites carried the ark of God with the poles on their shoulders, as Moses had commanded in accordance with the word of the LORD .

16David told the leaders of the Levites to appoint their fellow Levites as musicians to make a joyful sound with musical instruments: lyres, harps and cymbals.
