1 Chronicles 9:31-33

New Revised Standard Version Catholic Edition

³¹ and Mattithiah, one of the Levites, the firstborn of Shallum the Korahite, was in charge of making the flat cakes. ³² Also some of their kindred of the Kohathites had charge of the rows of bread, to prepare them for each sabbath.

³³ Now these are the singers, the heads of ancestral houses of the Levites, living in the chambers of the temple free from other service, for they were on duty day and night.
