Leviticus 10:7-17

7 You shall not go outside the entrance of the tent of meeting, or you will die; for the anointing oil of the Lord is on you." And they did as Moses had ordered.
8 And the Lord spoke to Aaron:
9 Drink no wine or strong drink, neither you nor your sons, when you enter the tent of meeting, that you may not die; it is 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 through Moses.
12 Moses spoke to Aaron and to his remaining sons, Eleazar and Ithamar: Take the grain offering that is left from the Lord's offerings by fire, and eat it unleavened beside the altar, for it is most holy;
13 you shall eat it in a holy place, because it is your due and your sons' due, from the offerings by fire to the Lord; for so I am commanded.
14 But the breast that is elevated and the thigh that is raised, you and your sons and daughters as well may eat in any clean place; for they have been assigned to you and your children from the sacrifices of the offerings of well-being of the people of Israel.
15 The thigh that is raised and the breast that is elevated they shall bring, together with the offerings by fire of the fat, to raise for an elevation offering before the Lord; they are to be your due and that of your children forever, as the Lord has commanded.
16 Then Moses made inquiry about the goat of the sin offering, and—it had already been burned! He was angry with Eleazar and Ithamar, Aaron's remaining sons, and said,
17 "Why did you not eat the sin offering in the sacred area? For it is most holy, and God has given it to you that you may remove the guilt of the congregation, to make atonement on their behalf before the Lord.
