The sons of Amram: Aaron and Moses. And Aaron was separated so that he should sanctify the most holy things, he and his sons perpetually to burn incense before Jehovah, to minister to Him and to bless in His name perpetually.
and they stood up against Uzziah the king, and said to him, It is not for you, O Uzziah, to burn incense to Jehovah, but to the priests, the sons of Aaron, who are sanctified to burn incense; go out of the sanctuary, for you have trespassed; and it is not to your honor from Jehovah God.
And you shall take to yourself your brother Aaron, and his sons with him, from among the sons of Israel, for him to serve as priest to Me; Aaron, Nadab, and Abihu, Eleazar, and Ithamar, the sons of Aaron.
Take Aaron, and his sons with him, and the garments, and the anointing oil, and the bull of the sin offering, and the two rams, and the basket of unleavened things,
a memorial to the sons of Israel, so that a man, an alien, is not of the seed of Aaron shll not draw near to offer incense before Jehovah, and shall not be as Korah, and as his company; as Jehovah had spoken by the hand of Moses to him.
And he spoke to Korah, and to all his company, saying, In the morning Jehovah will know who are His, and him who is holy, and shall cause him to come near Him; even him whom He may choose, He will cause to come near to Him.
and put fire in them, and put incense on them before Jehovah tomorrow; and it shall be, the man whom Jehovah chooses, he shall be the holy one. You take too much, sons of Levi!
And you, and your sons with you, shall keep your priesthood, in everything that pertains to the altar, and to that inside the veil. And you shall serve; I have given you the priesthood as a service of gift; and the stranger who comes near shall be caused to die.
