Numbers 3:1-10

MLV(i) 1 Now these are the genealogies of Aaron and Moses in the day that Jehovah spoke with Moses in Mount Sinai: 2 And these are the names of the sons of Aaron: Nadab the firstborn and Abihu, Eleazar and Ithamar. 3 These are the names of the sons of Aaron, the priests who were anointed, whom he consecrated to minister in the priest's office. 4 And Nadab and Abihu died before Jehovah when they offered strange fire before Jehovah in the wilderness of Sinai and they had no sons. And Eleazar and Ithamar ministered in the priest's office in the presence of Aaron their father.
5 And Jehovah spoke to Moses, saying, 6 Bring the tribe of Levi near and set them before Aaron the priest, that they may minister to him. 7 And they will keep his charge and the charge of the whole congregation before the tent of meeting, to do the service of the tabernacle. 8 And they will keep all the furniture of the tent of meeting and the charge of the sons of Israel, to do the service of the tabernacle. 9 And you will give the Levites to Aaron and to his sons. They are entirely given to him from the sons of Israel. 10 And you will appoint Aaron and his sons and they will keep their priesthood. And the stranger who comes near will be put to death.
