Numbers 3:6 DBY

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 exercised the priesthood in the presence of Aaron their father.

⁵  And Jehovah spoke to 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 assembly, before the tent of meeting, to do the service of the tabernacle.

⁸  And they shall keep all the utensils of the tent of meeting, and the charge of the children of Israel, to do the service of the tabernacle.
