Leviticus 10:2-9

²So fire came out from before Yahweh and devoured them, and they died before Yahweh.

³Then Moses said to Aaron, “This is what Yahweh was talking about when he said, 'I will reveal my holiness to those who come near me. I will be glorified before all the people.'” Aaron did not say anything.

⁴Moses called Mishael and Elzaphan, the sons of Uzziel the uncle of Aaron, and said to them, “Come here and carry your brothers out of the camp from before the tabernacle.”

⁵So they came near and carried them, still wearing their priestly tunics, out of the camp, as Moses had instructed.

⁶Then Moses said to Aaron and to Eleazar and to Ithamar, his sons, “Do not let your hair on your heads hang loosely, and do not tear your clothes, so that you may not die, and so that Yahweh may not be angry with all the assembly. But allow your relatives, the entire house of Israel, to mourn for those whom the fire of Yahweh has set ablaze.

⁷You must not go out from the entrance of the tent of meeting, or you will die, for the anointing oil of Yahweh is on you.” So they acted according to Moses' instructions.

⁸Yahweh spoke to Aaron, saying,

⁹“Do not drink wine or strong drink, you, or your sons who remain with you, when you go into the tent of meeting, so you will not die. This will be a permanent statute throughout your people's generations,
