Leviticus 10:2-9

²Fire came out from the Lord's presence and burned them up. They died in the Lord's presence.

³Moses explained to Aaron, “This is what the Lord was talking about when he said: ‘I will show my holiness to those who approach me; I will reveal my glory so everyone can see.” But Aaron didn't reply.

⁴Moses called Mishael and Elzaphan, sons of Aaron's uncle Uzziel, and told them, “Come and carry away the bodies of your cousins and take them outside the camp, away from the front of the sanctuary.”

⁵They came and picked them up by their clothes, and took them outside the camp, as Moses had ordered.

⁶Then Moses told Aaron and his sons Eleazar and Ithamar, “Don't leave your hair uncombed, and don't tear your clothes in mourning, otherwise you will die, and the Lord will be angry with everyone. But your relatives and all the other Israelites may mourn for those the Lord killed by fire.

⁷Don't go outside the entrance to the Tent of Meeting, or you will die, because you have been anointed by the Lord.” They did what Moses said.

⁸The Lord told Aaron,

⁹“You and your descendants must not to drink wine or any other alcohol when you go in to the Tent of Meeting, otherwise you will die. This regulation is for all time and for all future generations.
