1 Chronicles 9:26-33
9:26 The four head gatekeepers, who were Levites, were assigned to guard the storerooms and treasuries in God’s sanctuary.
9:27 They would spend the night in their posts all around God’s sanctuary, for they were assigned to guard it and would open it with the key every morning.
9:28 Some of them were in charge of the articles used by those who served; they counted them when they brought them in and when they brought them out.
9:29 Some of them were in charge of the equipment and articles of the sanctuary, as well as the flour, wine, olive oil, incense, and spices.
9:30 (But some of the priests mixed the spices.)
9:31 Mattithiah, a Levite, the firstborn son of Shallum the Korahite, was in charge of baking the bread for offerings.
9:32 Some of the Kohathites, their relatives, were in charge of preparing the bread that is displayed each Sabbath.
9:33 The musicians and Levite family leaders stayed in rooms at the sanctuary and were exempt from other duties, for day and night they had to carry out their assigned tasks.
