The Sons of Aaron

1This is the lineage of Aaron and Moses at the time when the LORD spoke with Moses on Mount Sinai. 2These are the names of the sons of Aaron: Nadab the firstborn, and Abihu, Eleazar, and Ithamar; 3these are the names of the sons of Aaron, the anointed priests, whom he ordained to minister as priests. 4Nadab and Abihu died before the LORD when they offered unholy fire before the LORD in the wilderness of Sinai, and they had no children. Eleazar and Ithamar served as priests in the lifetime of their father Aaron.

The Duties of the Levites

5Then the LORD spoke to Moses, saying: 6Bring the tribe of Levi near, and set them before Aaron the priest, so that they may assist him. 7They shall perform duties for him and for the whole congregation in front of the tent of meeting, doing service at the tabernacle; 8they shall be in charge of all the furnishings of the tent of meeting, and attend to the duties for the Israelites as they do service at the tabernacle. 9You shall give the Levites to Aaron and his descendants; they are unreservedly given to him from among the Israelites. 10But you shall make a register of Aaron and his descendants; it is they who shall attend to the priesthood, and any outsider who comes near shall be put to death.

11Then the LORD spoke to Moses, saying: 12I hereby accept the Levites from among the Israelites as substitutes for all the firstborn that open the womb among the Israelites. The Levites shall be mine, 13for all the firstborn are mine; when I killed all the firstborn in the land of Egypt, I consecrated for my own all the firstborn in Israel, both human and animal; they shall be mine. I am the LORD.

A Census of the Levites

14Then the LORD spoke to Moses in the wilderness of Sinai, saying: 15Enrol the Levites by ancestral houses and by clans. You shall enrol every male from a month old and upwards. 16So Moses enrolled them according to the word of the LORD, as he was commanded. 17The following were the sons of Levi, by their names: Gershon, Kohath, and Merari. 18These are the names of the sons of Gershon by their clans: Libni and Shimei. 19The sons of Kohath by their clans: Amram, Izhar, Hebron, and Uzziel. 20The sons of Merari by their clans: Mahli and Mushi. These are the clans of the Levites, by their ancestral houses.

21To Gershon belonged the clan of the Libnites and the clan of the Shimeites; these were the clans of the Gershonites. 22Their enrolment, counting all the males from a month old and upwards, was seven thousand five hundred. 23The clans of the Gershonites were to camp behind the tabernacle on the west, 24with Eliasaph son of Lael as head of the ancestral house of the Gershonites. 25The responsibility of the sons of Gershon in the tent of meeting was to be the tabernacle, the tent with its covering, the screen for the entrance of the tent of meeting, 26the hangings of the court, the screen for the entrance of the court that is around the tabernacle and the altar, and its cords—all the service pertaining to these.

27To Kohath belonged the clan of the Amramites, the clan of the Izharites, the clan of the Hebronites, and the clan of the Uzzielites; these are the clans of the Kohathites. 28Counting all the males, from a month old and upwards, there were eight thousand six hundred, attending to the duties of the sanctuary. 29The clans of the Kohathites were to camp on the south side of the tabernacle, 30with Elizaphan son of Uzziel as head of the ancestral house of the clans of the Kohathites. 31Their responsibility was to be the ark, the table, the lampstand, the altars, the vessels of the sanctuary with which the priests minister, and the screen—all the service pertaining to these. 32Eleazar son of Aaron the priest was to be chief over the leaders of the Levites, and to have oversight of those who had charge of the sanctuary.

33To Merari belonged the clan of the Mahlites and the clan of the Mushites: these are the clans of Merari. 34Their enrolment, counting all the males from a month old and upwards, was six thousand two hundred. 35The head of the ancestral house of the clans of Merari was Zuriel son of Abihail; they were to camp on the north side of the tabernacle. 36The responsibility assigned to the sons of Merari was to be the frames of the tabernacle, the bars, the pillars, the bases, and all their accessories—all the service pertaining to these; 37also the pillars of the court all around, with their bases and pegs and cords.

38Those who were to camp in front of the tabernacle on the east—in front of the tent of meeting towards the east—were Moses and Aaron and Aaron's sons, having charge of the rites within the sanctuary, whatever had to be done for the Israelites; and any outsider who came near was to be put to death. 39The total enrolment of the Levites whom Moses and Aaron enrolled at the commandment of the LORD, by their clans, all the males from a month old and upwards, was twenty-two thousand.

The Redemption of the Firstborn

40Then the LORD said to Moses: Enrol all the firstborn males of the Israelites, from a month old and upwards, and count their names. 41But you shall accept the Levites for me—I am the LORD—as substitutes for all the firstborn among the Israelites, and the livestock of the Levites as substitutes for all the firstborn among the livestock of the Israelites. 42So Moses enrolled all the firstborn among the Israelites, as the LORD commanded him. 43The total enrolment, all the firstborn males from a month old and upwards, counting the number of names, was twenty-two thousand two hundred and seventy-three.

44Then the LORD spoke to Moses, saying: 45Accept the Levites as substitutes for all the firstborn among the Israelites, and the livestock of the Levites as substitutes for their livestock; and the Levites shall be mine. I am the LORD. 46As the price of redemption of the two hundred and seventy-three of the firstborn of the Israelites, over and above the number of the Levites, 47you shall accept five shekels apiece, reckoning by the shekel of the sanctuary, a shekel of twenty gerahs. 48Give to Aaron and his sons the money by which the excess number of them is redeemed. 49So Moses took the redemption money from those who were over and above those redeemed by the Levites; 50from the firstborn of the Israelites he took the money, one thousand three hundred and sixty-five shekels, reckoned by the shekel of the sanctuary; 51and Moses gave the redemption money to Aaron and his sons, according to the word of the LORD, as the LORD had commanded Moses.
