1st Chronicles 9:30

27 and round about the house of God they lodge, for on them [is] the watch, and they [are] over the opening, even morning by morning.

28 And [some] of them [are] over the vessels of service, for by number they bring them in, and by number they take them out.

29 And [some] of them are appointed over the vessels, even over all the vessels of the sanctuary, and over the fine flour, and the wine, and the oil, and the frankincense, and the spices.

30 And [some] of the sons of the priests are mixing the mixture for spices.

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.
