²⁶  And the hangings for the open space round the House and the altar, and the curtain for its doorway, with the cords and all the things used for them; whatever is necessary for these, they are to do.

²⁷  From the mouth of Aaron and his sons the Gershonites will have word about all the things they are to do and take up; you are to give them their orders.

²⁸  This is the work of the family of the Gershonites in the Tent of meeting, and they will be under the direction of Ithamar, the son of Aaron the priest.

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.
