Leviticus 10:2-9

²So suddenly a fire from Yahweh appeared and burned them up DOU in the presence of Yahweh.

³Then Moses/I said to Aaron, “That is what Yahweh predicted. He said, ‘Those priests who come near to me, I will show them that they must ◄respect me/treat me as being holy►; in the presence of all the people I am the one who must be honored.’” But Aaron said nothing.

⁴Then Moses/I summoned Mishael and Elzaphan, who were the sons of Aaron's uncle Uzziel, and said to them, “Take the corpses of your cousins outside the camp, away from the front of the Sacred Tent.”

⁵So they carried the corpses, which still had their special gowns on, outside the camp, and buried them.

⁶Then Moses/I said to Aaron and his other two sons Eleazar and Ithamar, “ You are sad because Nadab and Abihu died, but you must act like you always do. Do not allow the hair on your heads to remain uncombed, and do not tear your clothes. But your relatives and all your fellow Israelis are allowed to mourn for those whom Yahweh destroyed by fire.

⁷But you must not leave the entrance of the Sacred Tent to join those who are mourning, because if you do that, you also will die, and Yahweh will punish MTY all the people of Israel. Do not forget that Yahweh has set you apart MTY to work for him here, and he does not want you to become defiled by touching a corpse.” So they did what Moses/I told them to do.

⁸Then Yahweh said to Aaron,

⁹“You and your two sons who are still alive must not drink wine or other fermented drinks before you enter the Sacred Tent; if you do that, you will die. That is a command that you and your descendants must obey forever.
