“And the Lord spake unto Moses in the wilderness of Sinai, saying, ‘Number the children of Levi after the house of their fathers, by their families, every male from a month old and upward shalt thou number them.’ And Moses numbered them _according to the word of the Lord, as he was commanded_. And these were the sons of Levi by their names: Gershon and Kohath and Merari. And these are the names of the sons of Gershon by their families: Libni and Shimei. And the sons of Kohath by their families: Amram and Izehar, Hebron and Uzziel. And the sons of Merari by their families: Mahli and Mushi. These are the families of the Levites according to the house of their fathers. Of Gershon was the family of the Libnites, and the family of the Shimites: these are the families of the Gershonites. Those that were numbered of them, according to the number of all the males, from a month old and upward, even those that were numbered of them were seven thousand and five hundred. The families of the Gershonites shall pitch behind the tabernacle westward. And the chief of the house of the father of the Gershonites shall be Eliasaph the son of Lael. And the charge of the sons of Gershon in the tabernacle of the congregation shall be the tabernacle, and the tent, the covering thereof, and the hanging for the door of the tabernacle of the congregation, and the hangings of the court, and the curtain for the door of the court, which is by the tabernacle, and by the altar round about, and the cords of it for all the service thereof.” (Chap. iii. 14-26.) And again, we read, “And the Lord spake unto Moses, saying, ‘Take also the sum of the sons of Gershon, throughout the houses of their fathers, by their families; from thirty years old and upward until fifty years old shalt thou number them; all that enter in to perform the service, to do the work in the tabernacle of the congregation. This is the service of the families of the Gershonites, to serve, and for burdens: and they shall bear the curtains of the tabernacle, and the tabernacle of the congregation, his covering, and the covering of the badgers’ skins that is above upon it, and the hanging for the door of the tabernacle of the congregation, and the hangings of the court, and the hanging for the door of the gate of the court, which is by the tabernacle and by the altar round about, and their cords, and all the instruments of their service, and all that is made for them: so shall they serve. At the appointment of Aaron and his sons shall be all the service of the sons of the Gershonites, in all their burdens, and in all their service: and ye shall appoint unto them in charge all their burdens. This is the service of the families of the sons of Gershon in the tabernacle of the congregation: and their charge shall be under the hand of Ithamar the son of Aaron the priest.” (Chap. iv. 21-28.)
