Numbers 3:35

32 Eleazar, the son of Aaron the priest, will be head over all the Levites and overseer of those responsible for the care of the holy place.

33 From Merari come the Mahlites and the Mushites; these are the families of Merari.

34 Those who were numbered of them, the males of a month old and over, were six thousand, two hundred.

35 The chief of the families of Merari was Zuriel, the son of Abihail: their tents are to be placed on the north side of the House.

36 And in their care are to be all the boards of the Tent, with their rods and pillars and bases, and all the instruments, and all they are used for,

37 And the pillars of the open space round it, with their bases and nails and cords.

38 And those whose tents are to be placed on the east side of the House in front of the Tent of meeting, looking to the dawn, are Moses and Aaron and his sons, who will do the work of the holy place for the children of Israel; and any strange person who comes near will be put to death.
