³¹ And Mattithiah, of the Levites (he [is] the first-born to Shallum the Korahite), [is] in office over the work of the pans.

³² And of the sons of the Kohathite, [some] of their brethren [are] over the bread of the arrangement, to prepare [it] sabbath by sabbath.

³³ And these who sing, heads of fathers of the Levites, in the chambers, [are] free, for by day and by night [they are] over them in the work.
