2 Chronicles 8:14-15

14In keeping with the ordinances of his father David, Solomon appointed the divisions of the priests over their service, and the Levites for their duties to offer praise and to minister before the priests according to the daily requirement. He also appointed gatekeepers by their divisions at each 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 or the Levites in any matter, including that of the treasuries.
