1 Chronicles 9:31-33

Modern English Version

³¹ Mattithiah, one of the Levites (he was the firstborn of Shallum the Korahite), was entrusted with making the flat cakes. ³² Others of the sons of the Kohathites and from their brothers were given charge over the showbread to prepare it every Sabbath.

³³ Now these are the singers, heads of the fathers’ houses of the Levites, who stayed in the temple chambers, free from other service, because they were occupied with the work day and night.
