Numbers 3:27-37

27 And of Kohath [is] the family of the Amramite, and the family of the Izharite, and the family of the Hebronite, and the family of the Uzzielite; these are families of the Kohathite.
28 In number, all the males, from a son of a month and upward, [are] eight thousand and six hundred, keeping the charge of the sanctuary.
29 The families of the sons of Kohath encamp by the side of the tabernacle southward.
30 And the prince of a father's house for the families of the Kohathite [is] Elizaphan son of Uzziel.
31 And their charge [is] the ark, and the table, and the candlestick, and the altars, and the vessels of the sanctuary with which they serve, and the vail, and all its service.
32 And [to] the prince of the princes of the Levites, Eleazar son of Aaron the priest, [is] the oversight of the keepers of the charge of the sanctuary.
33 Of Merari [is] the family of the Mahlite, and the family of the Mushite; these [are] the families of Merari.
34 And their numbered ones, in number, all the males from a son of a month and upward, [are] six thousand and two hundred.
35 And the prince of a father's house for the families of Merari [is] Zuriel son of Abihail; by the side of the tabernacle they encamp northward.
36 And the oversight -- the charge of the sons of Merari -- [is] the boards of the tabernacle, and its bars, and its pillars, and its sockets, and all its vessels, and all its service,
37 and the pillars of the court round about, and their sockets, and their pins, and their cords.
