The sons of Amram: Aaron and Moses. Aaron was set apart to consecrate the most holy things, that he and his sons for ever should burn incense before the Lord, and minister to him and pronounce blessings in his name for ever.
and they withstood King Uzziah, and said to him, “It is not for you, Uzziah, to burn incense to the Lord, but for the priests the sons of Aaron, who are consecrated to burn incense. Go out of the sanctuary; for you have done wrong, and it will bring you no honor from the Lord God.”
“Then bring near to you Aaron your brother, and his sons with him, from among the people of Israel, to serve me as priests—Aaron and Aaron's sons, Nadab and Abihu, Eleazar and Ithamar.
“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 bread;
to be a reminder to the people of Israel, so that no one who is not a priest, who is not of the descendants of Aaron, should draw near to burn incense before the Lord, lest he become as Korah and as his company—as the Lord said to Eleazar through Moses.
and he said to Korah and all his company, “In the morning the Lord will show who is his, and who is holy, and will cause him to come near to him; him whom he will choose he will cause to come near to him.
put fire in them and put incense upon them before the Lord tomorrow, and the man whom the Lord chooses shall be the holy one. You have gone too far, sons of Levi!”
And you and your sons with you shall attend to your priesthood for all that concerns the altar and that is within the veil; and you shall serve. I give your priesthood as a gift, and any one else who comes near shall be put to death.”
