4 But Nadab and Abihu died before the Lord, when they offered strange fire before the Lord, in the wilderness of Sinai, and they had no sons; and Eleazar and Ithamar exercised the priesthood in the sight of Aaron, their father.
5 And the Lord spoke unto Moses, saying,
6 Bring the tribe of Levi near and present them before Aaron, the priest, that they may minister unto him.
7 And they shall keep his commandment and the commandment of the whole congregation before the tabernacle of the testimony, to minister in the service of the tabernacle.
8 And they shall keep all the instruments of the tabernacle of the testimony and the charge of the sons of Israel, to minister in the service of the tabernacle.
9 And thou shalt give the Levites unto Aaron and to his sons; they are completely given unto him out of the sons of Israel.
10 And thou shalt appoint Aaron and his sons that they shall guard their priesthood; and the stranger that comes near shall be put to death.
