Leviticus 10:4-7

10:4 Moses then called to Mishael and Elzaphan, the sons of Uzziel, Aaron’s uncle, and said to them, “Come near, carry your brothers away from the front of the sanctuary to a place outside the camp.” 10:5 So they came near and carried them away in their tunics to a place outside the camp just as Moses had spoken. 10:6 Then Moses said to Aaron and to Eleazar and Ithamar his other two sons, “Do not dishevel the hair of your heads and do not tear your garments, so that you do not die and so that wrath does not come on the whole congregation. Your brothers, all the house of Israel, are to mourn the burning which the Lord has caused, 10:7 but you must not go out from the entrance of the Meeting Tent lest you die, for the Lord’s anointing oil is on you.” So they acted according to the word of Moses.
