29 “As for the sons of Merari, you shall number them by their families, by their fathers’ households; 30 from thirty years and upward even to fifty years old, you shall number them, everyone who enters the service to do the work of the tent of meeting. 31 Now this is the duty of their loads, for all their service in the tent of meeting: the boards of the tabernacle and its bars and its pillars and its sockets, 32 and the pillars around the court and their sockets and their pegs and their cords, with all their equipment and with all their service; and you shall assign each man by name the items he is to carry. 33 This is the service of the families of the sons of Merari, according to all their service in the tent of meeting, under the direction of Ithamar the son of Aaron the priest.”
