6 Then Moses said to Aaron and his sons Eleazar and Ithamar, “Do not let your hair become unkempt and do not tear your clothes, or you will die and the Lord will be angry with the whole community. But your relatives, all the Israelites, may mourn for those the Lord has destroyed by fire.
7 Do not leave the entrance to the tent of meeting or you will die, because the Lord’s anointing oil is on you.” So they did as Moses said.
8 Then the Lord said to Aaron,
9 “You and your sons are not to drink wine or other fermented drink whenever you go into the tent of meeting, or you will die. This is a lasting ordinance for the generations to come,
10 so that you can distinguish between the holy and the common, between the unclean and the clean,
11 and so you can teach the Israelites all the decrees the Lord has given them through Moses.”
12 Moses said to Aaron and his remaining sons, Eleazar and Ithamar, “Take the grain offering left over from the food offerings prepared without yeast and presented to the Lord and eat it beside the altar, for it is most holy.
