²⁶  and the hangings of the court, and the vail at the opening of the gate of the court which 'is' by the tabernacle, and by the altar round about, and their cords, and all the vessels of their service, and all that is made for them -- and they have served.

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.

²⁸  This '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;

³⁰  from 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.
