1 Chronicles 9:31-33

American Standard Version

³¹ And Mattithiah, one of the Levites, who was the first-born of Shallum the Korahite, had the office of trust over the things that were baked in pans. ³² And some of their brethren, of the sons of the Kohathites, were over the showbread, to prepare it every sabbath.

³³ And these are the singers, heads of fathers’ houses of the Levites, who dwelt in the chambers and were free from other service; for they were employed in their work day and night.
