1 Chronicles 9:31-33

New King James Version

³¹ Mattithiah of the Levites, the firstborn of Shallum the Korahite, had the trusted office ^(A)over the things that were baked in the pans. ³² And some of their brethren of the sons of the Kohathites ^(B)were in charge of preparing the showbread for every Sabbath.

³³ These are ^(C)the singers, heads of the fathers’ houses of the Levites, who lodged in the chambers, and were free from other duties; for they were employed in that work day and night.
