4 Now Nadab and Abiu died, without children, when they offered strange fire before the Lord, in the desert of Sinai: and Eleazar and Ithamar performed the priestly office in the presence of Aaron their father.
5 And the Lord spoke to Moses, saying:
6 Bring the tribe of Levi, and make them stand in the sight of Aaron the priest to minister to him, and let them watch,
7 And observe whatsoever appertaineth to the service of the multitude before the tabernacle of the testimony,
8 And let them keep the vessels of the tabernacle, serving in the ministry thereof.
9 And thou shalt give the Levites for a gift,
10 To Aaron and to his sons, to whom they are delivered by the children of Israel. But thou shalt appoint Aaron and his sons over the service of priesthood. The stranger that approacheth to minister, shall be put to death.
