2 Chronicles 8:14-15

14According to the ordinances of his father David, he appointed the divisions of the priests over their service, of the Levites over their responsibilities to offer praise and to minister before the priests following the daily requirement, and of the gatekeepers by their divisions with respect to each temple gate, for this had been the command of David, the man of God.

15They did not turn aside from the king’s command regarding the priests and the Levites concerning any matter or concerning the treasuries.
