Leviticus 10:3-11

3Then Moses said to Aaron, “It is what the Lord spoke, saying, ‘By those who 1come near Me I 23will be treated as holy, And before all the people I will 4be honored.’” So Aaron, therefore, kept silent.

4Moses called also to 5Mishael and Elzaphan, the sons of Aaron’s uncle Uzziel, and said to them, “Come forward, carry your relatives away from the front of the sanctuary to an area outside of the camp.” 5So they came forward and carried them, still in their 6tunics, to an area outside the camp, just as Moses had said. 6Then Moses said to Aaron and to his sons Eleazar and Ithamar, “7Do not 8uncover your heads nor tear your clothes, so that you do not die and He does not 9become wrathful against all the congregation. But your 10kinsmen, the entire house of Israel, shall weep for the burning which the Lord has 11brought about. 7You shall not even go out from the doorway of the tent of meeting, or you will die; for 12the Lord’s anointing oil is upon you.” So they did according to the word of Moses.

8The Lord then spoke to Aaron, saying, 9“13Do not drink wine or strong drink, neither you nor your sons with you, when you come into the tent of meeting, so that you do not die--it is a permanent statute throughout your generations-- 10and 14to make a distinction between the holy and the profane, and between the unclean and the clean, 11and 15so as to teach the sons of Israel all the statutes which the Lord has spoken to them through Moses.”
