1 Chronicles 9:26-33

26but the four chief gatekeepers, who were Levites, were entrusted with the rooms and the treasuries of God’s temple.

27They spent the night in the vicinity of God’s temple, because they had guard duty and were in charge of opening it every morning.

28Some of them were in charge of the utensils used in worship. They would count them when they brought them in and when they took them out.

29Others were put in charge of the furnishings and all the utensils of the sanctuary, as well as the fine flour, wine, oil, incense, and spices.

30Some of the priests’ sons mixed the spices.

31A Levite called Mattithiah, the firstborn of Shallum the Korahite, was entrusted with baking the bread.

32Some of the Kohathites’ relatives were responsible for preparing the rows of the Bread of the Presence every Sabbath.

33The singers, the heads of the Levite families, stayed in the temple chambers and were exempt from other tasks because they were on duty day and night.
