1 This is the account concerning Aaron and Moses when the Lord spoke to Moses on Mount Sinai. 2 The names of the sons of Aaron were: Nadab (firstborn), Abihu, Eleazar, and Ithamar. 3 These were the names of Aaron's sons who were anointed and ordained to serve as priests.

4 Nadab and Abihu died in the Lord's presence when they offered forbidden fire before the Lord in the Sinai desert. Since they didn't have any sons, Eleazar and Ithamar served as priests while their father Aaron was alive.

5 The Lord told Moses, 6 “Gather the tribe of Levi together and present them to Aaron the priest to help him with the ministry. 7 They are to carry out duties on his behalf and for all the Israelites at the Tent of Meeting, looking after the service of the Tabernacle. 8 They are responsible for caring for all the furniture of the Tent of Meeting, serving the Israelites through what they do in the Tabernacle. 9 The Levites are to work exclusively for Aaron and his sons of because this is their assignment among the Israelites. 10 You are to appoint Aaron and his sons to have the responsibility of the priesthood. Anyone else who tries to act as a priest must be executed.”

11 The Lord told Moses, 12 “I've taken the Levites from the Israelites in place of every one of their firstborn. The Levites belong to me 13 because all the firstborn are mine. When I killed every firstborn in Egypt I set apart as holy to me all the firstborn of Israel, human and animal. They are mine. I am the Lord.”

14 The Lord spoke to Moses in the Sinai desert. He told him, 15 “Register the Levites by their father's line and family. Count every male aged one month or older.” 16 So Moses registered them following the Lord's instructions, just as he had been told.

17 These were the names of Levi's sons: Gershon, Kohath, and Merari. 18 These were the names of the Gershon's sons by family: Libni and Shimei. 19 Kohath's sons by family were Amram, Izhar, Hebron, and Uzziel. 20 Merari's sons by family were Mahli and Mushi. These were the families of the Levites, according to their father's line.

21 The family of Libni and the family of Shimei came from Gershon. These were the families of Gershon. 22 The total of all males aged one month or older was 7,500. 23 The camp of families of Gerson was to the west, behind the Tabernacle. 24 The leader of the Gershon families was Eliasaph, son of Lael. 25 Their assigned responsibility for the Tent of Meeting was to take care of the Tabernacle and tent, its covering, the curtain at the entrance of the Tent of Meeting, 26 the courtyard curtains, the curtain at the entrance to the courtyard surrounding the Tabernacle and altar, the ropes, and everything connected with their use.

27 The families of Amram, Izhar, Hebron, and Uzziel came from Kohath. These were the families of Kohath. 28 The total of all males aged one month or older was 8,600. Their assigned responsibility was to take care of the sanctuary. 29 The camp of families of Kohath was on the south side of the Tabernacle. 30 The leader of the Kohath families was Elizaphan son of Uzziel. 31 Their assigned responsibility was to care for the Ark, the table, the lampstand, the altars, the articles of the sanctuary used with them, the veil, and everything connected with these items. 32 The chief of the leaders of the Levites was Eleazar, son of Aaron the priest. He was in charge of those responsible for serving in the sanctuary.

33 The family of Mahli and the family of Mushi came from Merari. These were the families of Merari. 34 The total of all males aged one month or older was 6,200. 35 The leader of the Merari families was Zuriel, son of Abihail. Their camp was on the north side of the Tabernacle. 36 Their assigned responsibility was to take care of the Tabernacle's frames, crossbars, posts, stands, all its equipment, and everything connected with their use, 37 as well as the posts of the surrounding courtyard with their stands, tent pegs, and ropes.

38 The camp of Moses, Aaron, and Aaron's sons was to the east of the Tabernacle, in the direction of the sunrise, in front of the Tent of Meeting. They were responsible for the sanctuary on behalf of the Israelites. Anyone else who tried to act as a priest was to be executed. 39 The sum total of Levites registered by Moses and Aaron as the Lord ordered was 22,000. This included all males aged one month or older.

40 The Lord told Moses, “Conduct a census of all the firstborn Israelite males aged one month or older, and register their names. 41 Assign the Levites to me. I am the Lord. They are in place of all of the Israelites' firstborn children. The livestock of the Levites are in place of all the Israelites' firstborn livestock.”

42 Moses conducted a census of all the firstborn of the Israelites, as the Lord had instructed him. 43 The sum total of the firstborn males a month old or more, registered by name, was 22,273.

44 The Lord spoke to Moses and told him, 45 “You are to take the Levites in place of all the firstborn children of Israel, and the livestock of the Levites in place of their livestock, because the Levites belong to me. I am the Lord. 46 In order to buy back the 273 firstborn Israelites who are more than the number of Levites, 47 collect five shekels for each of them, (using the sanctuary shekel standard of twenty gerahs). 48 He handed the money over to Aaron and his sons as the redemption price for the extra Israelites.” 49 Moses collected the redemption money for those extra Israelites that were more than the number redeemed by the Levites. 50 He collected the money given on behalf of the Israelites' firstborn children. It came to 1,365 shekels, (using the sanctuary shekel standard). 51 Moses gave this redemption money to Aaron and his sons as the Lord had told him to, following the Lord's instructions.
