1 Chronicles 15:12

And he said to them, “You are the heads of the Levitical families. You and your relatives must consecrate yourselves so that you may bring the ark of the LORD, the God of Israel, to the place I have prepared for it.

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.
