1This is the account of the family of Aaron and Moses at the time the LORD spoke to Moses at Mount Sinai.
2The names of Aaron's sons were Nadab the firstborn, Abihu, Eleazar, and Ithamar.
3These were the names of Aaron's sons, the anointed priests who were ordained to serve as priests.
4Nadab and Abihu died before the LORD when they made an unauthorized offering before him in the wilderness of Sinai. They had no sons, so Eleazar and Ithamar served as priests during Aaron's lifetime.
5The LORD said to Moses,
6"Bring the tribe of Levi and present them to Aaron the priest, to assist him."
7"They are to perform duties for him and for the whole community at the tent of meeting by doing the work of the tabernacle."
8"They are to take care of all the furnishings of the tent of meeting and fulfill their responsibilities on behalf of the Israelites by doing the work of the tabernacle."
9"Give the Levites to Aaron and his sons; they are the Israelites who are to be wholly given over to him."
10"Appoint Aaron and his sons to serve as priests; anyone else who approaches the sanctuary is to be put to death."
11The LORD also said to Moses,
12"I have taken the Levites from among the Israelites in place of every firstborn male. The Levites are mine,"
13"for every firstborn belongs to me. When I struck down every firstborn in Egypt, I set apart for myself every firstborn in Israel, both human and animal. They are mine. I am the LORD."
14The LORD said to Moses in the wilderness of Sinai,
15"Count the Levites by their families and clans. Count every male a month old or more."
16So Moses counted them, as the LORD commanded.
17These were the sons of Levi by name: Gershon, Kohath, and Merari.
18The sons of Gershon by clan were Libni and Shimei.
19The sons of Kohath by clan were Amram, Izhar, Hebron, and Uzziel.
20The sons of Merari by clan were Mahli and Mushi. These were the Levite clans according to their families.
21From Gershon came the clans of Libni and Shimei; these were the Gershonite clans.
22The total number of all the males a month old or more who were counted was 7,500.
23The Gershonite clans were to camp on the west side of the tabernacle.
24The leader of the Gershonite families was Eliasaph son of Lael.
25The Gershonites were responsible for the tabernacle, its tent, its covering, the curtain at the entrance of the tent of meeting,
26the courtyard curtains, the curtain at the entrance to the courtyard that surrounds the tabernacle and altar, and the ropes — and everything related to their use.
27From Kohath came the clans of Amram, Izhar, Hebron, and Uzziel; these were the Kohathite clans.
28The total number of all the males a month old or more was 8,600. The Kohathites were responsible for the care of the sanctuary.
29The Kohathite clans were to camp on the south side of the tabernacle.
30The leader of the Kohathite families was Elizaphan son of Uzziel.
31They were responsible for the ark, the table, the lampstand, the altars, the sanctuary utensils used in the ministry, the curtain, and everything related to their use.
32Eleazar son of Aaron the priest was to be chief over the Levite leaders and have overall responsibility for those who cared for the sanctuary.
33From Merari came the clans of Mahli and Mushi; these were the Merarite clans.
34The total number of all the males a month old or more who were counted was 6,200.
35The leader of the Merarite families was Zuriel son of Abihail; they were to camp on the north side of the tabernacle.
36The Merarites were assigned custody of the frames of the tabernacle, its crossbars, posts, bases, all its equipment, and everything related to their use,
37as well as the posts of the surrounding courtyard with their bases, tent pegs, and ropes.
38Moses, Aaron, and his sons were to camp to the east of the tabernacle, toward the sunrise, in front of the tent of meeting. They were responsible for the sanctuary on behalf of the Israelites. Anyone else who approached the sanctuary was to be put to death.
39The total number of Levites counted by Moses and Aaron at the LORD's command, according to their clans, including every male a month old or more, was 22,000.
40The LORD said to Moses, "Count all the firstborn Israelite males who are a month old or more and make a list of their names."
41"Take the Levites for me in place of all the firstborn of the Israelites, and the livestock of the Levites in place of all the firstborn livestock of the Israelites. I am the LORD."
42So Moses counted all the firstborn Israelite males, as the LORD commanded him.
43The total number of firstborn males a month old or more, listed by name, was 22,273.
44The LORD also said to Moses,
45"Take the Levites in place of all the firstborn of Israel, and the livestock of the Levites in place of their livestock. The Levites are to be mine. I am the LORD."
46"To redeem the 273 firstborn Israelites who exceed the number of the Levites,"
47"collect five shekels for each one, according to the sanctuary shekel — which weighs twenty gerahs."
48"Give the money for the redemption of the additional Israelites to Aaron and his sons."
49So Moses collected the redemption money from those who exceeded the number redeemed by the Levites.
50From the firstborn of the Israelites he collected silver weighing 1,365 shekels, according to the sanctuary shekel.
51Moses gave the redemption money to Aaron and his sons, as the LORD commanded him.
