6 And Moses said to Aaron and to Eleazar and Ithamar his sons, “Do not let the hair of your heads hang loose, and do not tear your clothes, lest you die, and wrath come upon all the congregation; but let your brothers, the whole house of Israel, bewail the burning that the Lord has kindled.
7 And do not go outside the entrance of the tent of meeting, lest you die, for the anointing oil of the Lord is upon you.” And they did according to the word of Moses.
8 And the Lord spoke to Aaron, saying,
9 “Drink no wine or strong drink, you or your sons with you, when you go into the tent of meeting, lest you die. It shall be a statute forever throughout your generations.
10 You are to distinguish between the holy and the common, and between the unclean and the clean,
11 and you are to teach the people of Israel all the statutes that the Lord has spoken to them by Moses.”
12 Moses spoke to Aaron and to Eleazar and Ithamar, his surviving sons: “Take the grain offering that is left of the Lord’s food offerings, and eat it unleavened beside the altar, for it is most holy.
