Leviticus 10:16-20 - The Problem Of The Uneaten Sin Offering
16 And Moses carefully looked for the goat of the sin offering. And behold, it was burned! And he was angry with Eleazar and Ithamar, the sons of Aaron left alive, saying, 17 Why have you not eaten the sin offering in the holy place, since it is most holy, and He has given it to you to bear the iniquity of the congregation, to make atonement for them before Jehovah? 18 Behold! The blood of it was not brought within the holy place! You should indeed have eaten it in the sanctuary, as I commanded.
19 And Aaron said to Moses, Behold, this day they have offered their sin offering and their burnt offering before Jehovah. And such things have happened to me. And if I had eaten the sin offering today, should it have been accepted in the sight of Jehovah? 20 And Moses heard, and it was good in his eyes.
