Leviticus 10:3-11

10:3 Moses then said to Aaron, “This is what the Lord spoke: ‘Among the ones close to me I will show myself holy, and in the presence of all the people I will be honored.’” So Aaron kept silent. 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.

Perpetual Statutes the Lord Spoke to Aaron

10:8 Then the Lord spoke to Aaron, 10:9 “Do not drink wine or strong drink, you and your sons with you, when you enter into the Meeting Tent, so that you do not die, which is a perpetual statute throughout your generations, 10:10 as well as to distinguish between the holy and the common, and between the unclean and the clean, 10:11 and to teach the Israelites all the statutes that the Lord has spoken to them through Moses.”
