1 Chronicles 15:14

And said unto them, Ye are the chief of the fathers of the Levites: sanctify yourselves, both ye and your brethren, that ye may bring up the ark of the LORD God of Israel unto the place that I have prepared for it.

For because ye did it not at the first, the LORD our God made a breach upon us, for that we sought him not after the due order.

And the children of the Levites bare the ark of God upon their shoulders with the staves thereon, as Moses commanded according to the word of the LORD.

And David spake to the chief of the Levites to appoint their brethren to be the singers with instruments of musick, psalteries and harps and cymbals, sounding, by lifting up the voice with joy.
