And bring thou near unto thee Aaron thy brother, and his sons with him, from among the children of Israel, that he may minister unto me in the priest's office, even Aaron, Nadab and Abihu, Eleazar and Ithamar, Aaron's sons.
At that time Jehovah set apart the tribe of Levi, to bear the ark of the covenant of Jehovah, to stand before Jehovah to minister unto him, and to bless in his name, unto this day.
And the man that doeth presumptuously, in not hearkening unto the priest that standeth to minister there before Jehovah thy God, or unto the judge, even that man shall die: and thou shalt put away the evil from Israel.
