Leviticus 10:4-7

4Moses called Mishael and Elzaphan, the sons of Aaron’s uncle, Uzziel. He told them, “Come and take your relatives away from in front of the holy place. Take them outside the camp.”

5So they came and took them away to a place outside the camp, as Moses told them. The dead men were still in their linen robes.

6Moses told Aaron and his sons Eleazar and Ithamar: “Do not mourn by leaving your hair uncombed or tearing your clothes. If you do, you will die and the Lord will become angry with the whole congregation. All the other Israelites may cry over the fire the Lord sent, but you may not.

7You must not leave the entrance to the tent of meeting or else you, too, will die, because the Lord has anointed you with his oil.” They obeyed Moses.
