Numbers 3:14–24

14 And the Lord spoke to Moses in the wilderness of Sinai, saying, 15 “List the sons of Levi, by fathers’ houses and by clans; qevery male from a month old and upward you shall list.” 16 So Moses listed them according to the word of the Lord, as he was commanded. 17 rAnd these were the sons of Levi by their names: Gershon and Kohath and Merari. 18 And these are the names of the sons of Gershon by their clans: sLibni and Shimei. 19 And the sons of Kohath by their clans: tAmram, Izhar, Hebron, and Uzziel. 20 And the sons of Merari by their clans: uMahli and Mushi. These are the clans of the Levites, by their fathers’ houses.

21 To Gershon belonged the clan of the Libnites and the clan of the Shimeites; these were the clans of the Gershonites. 22 Their listing according to the number of all the males from a month old and upward was1 7,500. 23 vThe clans of the Gershonites were to camp behind the tabernacle on the west, 24 with Eliasaph, the son of Lael as chief of the fathers’ house of the Gershonites.
