Leviticus 10:14-20

14 And the waved breast and elevated shoulder shall ye likewise eat in a clean place, thou and thy sons and thy daughters with thee; for they are thy due and thy sons’ due, which are given out of the sacrifices of the peace of the sons of Israel.
15 With the offerings of the fat which are to be lit on fire, they shall bring the shoulder which is to be elevated and the breast which shall be waved as a wave offering before the LORD; and it shall be thine and thy sons’ with thee by a perpetual statute, as the LORD has commanded.
16 And Moses diligently sought the goat of the sin, and, behold, it was burnt up, and he was angry with Eleazar and Ithamar, the sons of Aaron who were left alive, saying,
17 Why have ye not eaten of the atonement for sin in the holy place? For it is most holy, and God has given it to you to bear the iniquity of the congregation, that they may be reconciled before the LORD.
18 Behold, the blood of it was not brought in within the inner sanctuary; ye should indeed have eaten it in the holy place, as I commanded.
19 And Aaron replied unto Moses, Behold, today they have offered their sin and their burnt offering before the LORD; with all this, these things have befallen me; therefore if I had eaten of the atonement for sin today, would it have been accepted in the sight of the LORD?
20 And when Moses heard that, he was content.
