1 Chronicles 9:22-33

22Altogether, those chosen to be gatekeepers at the thresholds numbered 212. They were registered by genealogy in their villages. The gatekeepers had been assigned to their positions of trust by David and Samuel the seer. 23They and their descendants were in charge of guarding the gates of the house of the LORD —the house called the tent of meeting. 24The gatekeepers were on the four sides: east, west, north and south. 25Their fellow Levites in their villages had to come from time to time and share their duties for seven-day periods. 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. 30But some of the priests took care of mixing the spices. 31A Levite named Mattithiah, the firstborn son of Shallum the Korahite, was entrusted with the responsibility for baking the offering bread.

32Some of the Kohathites, their fellow Levites, were in charge of preparing for every Sabbath the bread set out on the table.

33Those who were musicians, heads of Levite families, stayed in the rooms of the temple and were exempt from other duties because they were responsible for the work day and night.
