1. Now these are the records of Aaron and Moses when the Lord spoke with Moses on Mount Sinai.
2. These are the names of the sons of Aaron: Nadab, the firstborn, and Abihu, Eleazar, and Ithamar.
3. These are the names of the sons of Aaron, the anointed priests, whom he consecrated to minister as priests.
4. Nadab and Abihu died before the Lord when they offered strange fire before the Lord in the wilderness of Sinai, and they had no children. So Eleazar and Ithamar ministered as priests in the presence of Aaron their father.
5. The Lord spoke to Moses:
6. “Bring the tribe of Levi near, and present them before Aaron the priest, that they may serve him.
7. They are responsible for his needs and the needs of the whole community before the tent of meeting, by attending to the service of the tabernacle.
8. And they are responsible for all the furnishings of the tent of meeting, and for the needs of the Israelites, as they serve in the tabernacle.
9. You are to assign the Levites to Aaron and his sons; they will be assigned exclusively to him out of all the Israelites.
10. So you are to appoint Aaron and his sons, and they will be responsible for their priesthood; but the unauthorized person who comes near must be put to death.”
11. Then the Lord spoke to Moses:
12. “Look, I myself have taken the Levites from among the Israelites instead of every firstborn who opens the womb among the Israelites. So the Levites belong to me,
13. because all the firstborn are mine. When I destroyed all the firstborn in the land of Egypt, I set apart for myself all the firstborn in Israel, both man and beast. They belong to me. I am the Lord.”
14. Then the Lord spoke to Moses in the wilderness of Sinai:
15. “Number the Levites by their clans and their families; every male from a month old and upward you are to number.”
