²⁹ The sons of Merari are to be numbered by families, in the order of their fathers' houses; ³⁰ Every one from thirty to fifty years old who is able to do the work of the Tent of meeting. ³¹ And this is their part in the work of the Tent of meeting: the transport of the boards and the rods of the Tent, with the pillars and their bases; ³² And the pillars of the open space outside it, with their bases and their nails and cords and all the instruments used, and everything which has to be done there; all the instruments for which they are responsible are to be numbered by name. ³³ This is the work which the sons of Merari are to do in connection with the Tent of meeting, under the direction of Ithamar, the son of Aaron the priest.
