Aaron's Sons and the Duties of the Levites
31This is the family history of Aaron and Moses at the time when the Lord spoke with Moses on Mount Sinai.
2These are the names of Aaron's sons: Nadab the firstborn, Abihu, Eleazar, and Ithamar. 3These are the names of Aaron's sons, the anointed priests, whom he ordained to serve as priests.
4Nadab and Abihu died in the presence of the Lord when they offered unauthorized fire before the Lord in the Wilderness of Sinai, and they had no sons. So Eleazar and Ithamar served as priests in the presence of Aaron their father.
5The Lord spoke to Moses: 6“Bring the tribe of Levi near and have them stand before Aaron the priest so that they may assist him. 7They will perform the duties for him and for the entire congregation in front of the Tent of Meeting by doing the work for the Dwelling. 8They will take care of all the furnishings for the Tent of Meeting and perform the duties of the Israelites by doing the work for the Dwelling. 9You will give the Levites to Aaron and to his sons. They are completely given to him from among the Israelites. 10But you will appoint Aaron and his sons, and they will serve in the priesthood. Any unauthorized person who goes near must be put to death.”
The Census of the Levites for Assigning Their Duties
11The Lord spoke to Moses, 12“See, I have taken the Levites from among the Israelites instead of every firstborn that opens the womb among the Israelites. The Levites are mine, 13because all the firstborn are mine. On the day that I struck down all the firstborn in the land of Egypt, I set apart for myself every firstborn in Israel, both human and animal. They are mine. I am the Lord.”
14The Lord spoke to Moses in the Wilderness of Sinai, 15“Register the Levites according to their fathers' houses, by their clans. You are to register every male a month old and up.”
16So Moses registered them as he was commanded by the word of the Lord.
39All of the Levities who were registered when the Lord commanded Moses and Aaron to register them according to their clans, every male a month old and up, were 22,000.
Redemption of the Firstborn
40The Lord said to Moses, “Register all the firstborn males of the Israelites one month old and up, and make a list of their names. 41You are to take the Levites for me—I am the Lord—instead of every firstborn among the Israelites, and take the livestock of the Levites instead of every firstborn among the livestock of the Israelites.” 42So Moses registered all the firstborn among the Israelites as the Lord commanded. 43All the firstborn males listed by name, one month old and up, when registered, totaled 22,273.
44The Lord spoke to Moses: 45“Take the Levites instead of every firstborn among the Israelites, and the livestock of the Levites instead of their livestock. The Levites will be mine. I am the Lord. 46For the redemption of the 273 firstborn Israelites who outnumber the Levites, 47you are to collect five shekels apiece for each one, according to the sanctuary shekel (this shekel is twenty gerahs).[] 48You are to give the money, the redemption price for the additional Israelites, to Aaron and his sons.”
