Leviticus 10:11

7 You shall not go outside the entrance to the Tent of Meeting, or you will die, for the LORD’s anointing oil is on you.” So they did as Moses instructed.

8 Then the LORD said to Aaron,

9 “You and your sons are not to drink wine or strong drink when you enter the Tent of Meeting, or else you will die; this is a permanent statute for the generations to come.

10 You must distinguish between the holy and the common, between the clean and the unclean,

11 so that you may teach the Israelites all the statutes that the LORD has given them through Moses.”

12 And Moses said to Aaron and his remaining sons, Eleazar and Ithamar, “Take the grain offering that remains from the offerings made by fire to the LORD and eat it without leaven beside the altar, because it is most holy.

13 You shall eat it in a holy place, because it is your share and your sons’ share of the offerings made by fire to the LORD; for this is what I have been commanded.

14 And you and your sons and daughters may eat the breast of the wave offering and the thigh of the contribution in a ceremonially clean place, because these portions have been assigned to you and your children from the peace offerings of the sons of Israel.

15 They are to bring the thigh of the contribution and the breast of the wave offering, together with the fat portions of the offerings made by fire, to wave as a wave offering before the LORD. It will belong permanently to you and your children, as the LORD has commanded.”
