1 Chronicles 9:31-33

Amplified Bible

³¹ Mattithiah, one of the Levites, the firstborn of Shallum the Korahite, was responsible for the things baked in pans. ³² Some of their Kohathite relatives were in charge of the showbread to prepare it every Sabbath.

³³ Now these are the singers, heads of the fathers’ households of the Levites, living in the temple chambers, free from other service because they were on duty day and night.
