Numbers 3:3–10
3 These are the names of the sons of Aaron, bthe priests which were anointed, †whom he consecrated to minister in the priest’s office. 4 cAnd 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.
5 And the Lord spake unto Moses, saying, 6 dBring the tribe of Levi near, and present them before Aaron the priest, that they may minister unto him. 7 And they shall keep his charge, and the charge of the whole congregation before the tabernacle of the congregation, eto do the service of the tabernacle. 8 And they shall keep all the instruments of the tabernacle of the congregation, and the charge of the children of Israel, eto do the service of the tabernacle. 9 And fthou shalt give the Levites unto Aaron and to his sons: they are wholly given unto him out of the children of Israel. 10 And thou shalt appoint Aaron and his sons, gand they shall wait on their priest’s office: hand the stranger that cometh nigh shall be put to death.
