3 These are the names of the sons of Aaron, the priests which were anointed, whom he consecrated to minister in the priest's office.
4 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.
5 And the Lord spake 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 charge, and the charge of the whole congregation before the tabernacle of the congregation, to 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, to do the service of the tabernacle.
9 And thou shalt give the Levites unto Aaron and to his sons; they are wholly given to him out of the children of Israel.
10 And thou shalt appoint Aaron and his sons, and they shall wait on their priest's office; and the stranger that cometh nigh shall be put to death.
11 And the Lord spake unto Moses, saying,
12 And I, behold, I have taken the Levites from among the children of Israel instead of all the first-born that openeth the matrix among the children of Israel; therefore the Levites shall be mine;
13 Because all the first-born are mine; for on the day that I smote all the first-born in the land of Egypt I hallowed unto me all the first-born in Israel, both man and beast; mine they shall be; I am the Lord.
