1 Chronicles 9:26-29

26But the four principal gatekeepers, who were Levites, were entrusted with the responsibility for the rooms and treasuries in the house of God.

27They would spend the night stationed around the house of God, because they had to guard it; and they had charge of the key for opening it each morning.

28Some of them were in charge of the articles used in the temple service; they counted them when they were brought in and when they were taken out.

29Others were assigned to take care of the furnishings and all the other articles of the sanctuary, as well as the special flour and wine, and the olive oil, incense and spices.
