1 Chronicles 9:26-32

Being Levites, they were responsible for the security of all supplies and valuables in the house of God. They kept watch all through the night and had the key to open the doors each morning. Some were in charge of the articles used in The Temple worship—they counted them both when they brought them in and when they took them out. Others were in charge of supplies in the sanctuary—flour, wine, oil, incense, and spices. And some of the priests were assigned to mixing the oils for the perfume. The Levite Mattithiah, the firstborn son of Shallum the Korahite, was responsible for baking the bread for the services of worship. Some of the brothers, sons of the Kohathites, were assigned to preparing the bread set out on the table each Sabbath.
