27`By the command of Aaron and his sons is all the service of the sons of the Gershonite in all their burden, and in all their service; and ye have laid a charge on them concerning the charge of all their burden.
28This [is] the service of the families of the sons of the Gershonite in the tent of meeting; and their charge [is] under the hand of Ithamar son of Aaron the priest.
29`The sons of Merari, by their families, by the house of their fathers, thou dost number them;
30from a son of thirty years and upward even unto a son of fifty years thou dost number them, every one who is going in to the host, to do the service of the tent of meeting.
31`And this [is] the charge of their burden, of all their service in the tent of meeting; the boards of the tabernacle, and its bars, and its pillars, and its sockets,
32and the pillars of the court round about, and their sockets, and their pins, and their cords, of all their vessels, and of all their service; and by name ye do number the vessels of the charge of their burden.
33`This [is] the service of the families of the sons of Merari, for all their service, in the tent of meeting, by the hand of Ithamar son of Aaron the priest.`
