Leviticus 10:11

9“You and your sons are not to drink wine or strong drink whenever you go into the Tent of Meeting, or you will die. This shall be a statute forever throughout your generations.

10You are to make a distinction between the holy and the common, and between the unclean and the clean.

11You are to teach the children of Israel all the statutes which the LORD has spoken to them by Moses.”

12Moses spoke to Aaron, and to Eleazar and to Ithamar, his sons who were left, “Take the meal offering that remains of the offerings of the LORD made by fire, and eat it without yeast beside the altar; for it is most holy;

13and you shall eat it in a holy place, because it is your portion, and your sons’ portion, of the offerings of the LORD made by fire; for so I am commanded.
