“Then bring near to you your brother Aaron and his sons with him, from among the Israelites, to serve me as priests—Aaron and Aaron’s sons: Nadab and Abihu, Eleazar and Ithamar.
a reminder to the Israelites that no outsider, who is not of the descendants of Aaron, shall approach to offer incense before the Lord, so as not to become like Korah and his congregation, just as the Lord had said to him through Moses.
Then he spoke to Korah and all his congregation, saying, “In the morning the Lord will make known who is his and who is holy and who will be allowed to approach him; the one whom he will choose he will allow to approach him.
But you and your sons with you shall diligently perform your priestly duties in all that concerns the altar and the area behind the curtain. I give your priesthood as a gift; any outsider who approaches shall be put to death.”
