4 And Nadab and Abihu died before the LORD, when they offered unholy fire before the LORD, in the wilderness of Sinai, and they had no children: and Eleazar and Ithamar ministered in the priest's office 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 perform his duties, and the duties of the whole congregation before the tabernacle of meeting, to do the work of the tabernacle.
8 And they shall keep all the furnishings of the tabernacle of meeting, and serve the children of Israel, to do the work of the tabernacle.
9 And you shall give the Levites unto Aaron and to his sons: they are wholly given unto him out of the children of Israel.
10 And you shall appoint Aaron and his sons, and they shall wait on their priest's office: and the stranger that comes near shall be put to death.
