And 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: and Eleazar and Ithamar ministered in the priest's office in the sight of Aaron their father.
And the LORD spake unto Moses, saying,
Bring the tribe of Levi near, and present them before Aaron the priest, that they may minister unto him.
And they shall keep his charge, and the charge of the whole congregation before the tabernacle of the congregation, to do the service of the tabernacle.
And they shall keep all the instruments of the tabernacle of the congregation, and the charge of the children of Israel, to do the service of the tabernacle.
And thou shalt give the Levites unto Aaron and to his sons: they are
wholly given unto him out of the children of Israel.
