Numbers 3:14-39 New American Bible (Revised Edition) (NABRE)
Census of the Levites. 14 The Lord said to Moses in the wilderness of Sinai: 15 Enroll the Levites by their ancestral houses and clans, enrolling every male of a month or more. 16 Moses, therefore, enrolled them at the direction of the Lord, just as the Lord had charged.
17 These were the sons of Levi by name: Gershon, Kohath and Merari. 18 These were the names of the sons of Gershon, by their clans: Libni and Shimei. 19 The sons of Kohath, by their clans, were Amram, Izhar, Hebron and Uzziel. 20 The sons of Merari, by their clans, were Mahli and Mushi. These were the clans of the Levites by their ancestral houses.
Duties of the Levitical Clans. 21 To Gershon belonged the clan of the Libnites and the clan of the Shimeites; these were the clans of the Gershonites. 22 Their enrollment, registering every male of a month or more, was seven thousand five hundred. 23 The clans of the Gershonites camped behind the tabernacle, to the west. 24 The leader of the ancestral house of the Gershonites was Eliasaph, son of Lael. 25 At the tent of meeting their responsibility was the tabernacle:[a] the tent and its covering, the curtain at the entrance of the tent of meeting, 26 the hangings of the court, the curtain at the entrance of the court enclosing both the tabernacle and the altar, and the ropes—whatever pertained to their maintenance.
27 To Kohath belonged the clans of the Amramites, the Izharites, the Hebronites, and the Uzzielites; these were the clans of the Kohathites. 28 Their enrollment, registering every male of a month or more, was eight thousand three hundred. They were the ones who performed the duties of the sanctuary. 29 The clans of the Kohathites camped on the south side of the tabernacle. 30 And the leader of their ancestral house of the clan of the Kohathites was Elizaphan, son of Uzziel. 31 Their responsibility was the ark, the table, the menorah, the altars, the utensils of the sanctuary with which the priests minister, the veil, and everything pertaining to their maintenance.[b] 32 The chief of the leaders of the Levites, however, was Eleazar, son of Aaron the priest; he was in charge of those who performed the duties of the sanctuary.
33 To Merari belonged the clans of the Mahlites and the Mushites; these were the clans of Merari. 34 Their enrollment, registering every male of a month or more, was six thousand two hundred. 35 The leader of the ancestral house of the clans of Merari was Zuriel, son of Abihail. They camped at the north side of the tabernacle. 36 [c]The Merarites were assigned responsibility for the boards of the tabernacle, its bars, columns, pedestals, and all its fittings—and everything pertaining to their maintenance, 37 as well as the columns of the surrounding court with their pedestals, pegs and ropes.
38 East of the tabernacle, that is, in front of the tent of meeting, toward the sunrise, were camped Moses and Aaron and the latter’s sons, performing the duties of the sanctuary incumbent upon the Israelites. Any unauthorized person who came near was to be put to death.
39 The total enrollment of the Levites whom Moses and Aaron enrolled at the direction of the Lord, by clans, every male a month old or more, was twenty-two thousand.
Numbers 26:57-62 New American Bible (Revised Edition) (NABRE)
Census of the Levites. 57 These were the Levites enrolled by clans: through Gershon, the clan of the Gershonites; through Kohath, the clan of the Kohathites; through Merari, the clan of the Merarites. 58 These were clans of Levi: the clan of the Libnites, the clan of the Hebronites, the clan of the Mahlites, the clan of the Mushites, the clan of the Korahites.[a]
Now Kohath begot Amram, 59 whose wife was named Jochebed. She was the daughter of Levi, born to Levi in Egypt. To Amram she bore Aaron and Moses and Miriam their sister. 60 To Aaron were born Nadab and Abihu, Eleazar and Ithamar. 61 But Nadab and Abihu died when they offered unauthorized fire before the Lord. 62 The Levites enrolled were twenty-three thousand, every male one month or more of age. They were not enrolled with the other Israelites, however, for no heritage was given them among the Israelites.
