Leviticus 10:6-7

⁶ Then Moses said to Aaron and to his sons Eleazar and Ithamar , " Do not uncover your heads nor tear your clothes , so that you will not die and that He will not become wrathful against all the congregation . But your kinsmen , the whole house of Israel , shall bewail the burning which the Lord has brought about. ⁷ "You shall not even go out from the doorway of the tent of meeting , or you will die ; for the Lord'S anointing oil is upon you." So they did according to the word of Moses .
