1 Chronicles 9:31-33

New International Version - UK

³¹ A Levite named Mattithiah, the firstborn son of Shallum the Korahite, was entrusted with the responsibility for baking the offering bread. ³² Some of the Kohathites, their fellow Levites, were in charge of preparing for every Sabbath the bread set out on the table.

³³ Those 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.
