ISV(i) 29 Others were responsible for the furniture and for all of the holy utensils, including the flour, wine, oil, incense, and spices. 30 Other descendants of the priests prepared the mixed spices. 31 Mattithiah, a descendant of Levi and firstborn of Shallum the Korahite, was in charge of making the offering cakes. 32 Some of their Kohathite relatives were responsible to prepare the rows of bread for each Sabbath. 33 These singers, leaders of ancestral households of the descendants of Levi, were living in the chambers of the Temple. Freed from other service responsibilities, they were on duty day and night. 34 These leaders of the descendants of Levi, enrolled according to their genealogies, lived in Jerusalem.
