Leviticus 10:16-10:20
Then Moses inquired about the goat of sin offering, and it had already been burned! He was angry with Eleazar and Ithamar, Aaron's remaining sons, and said, "Why did you not eat the sin offering in the sacred area? For it is most holy, and He has given it to you to remove the guilt of the community and to make expiation for them before the Lord. Since its blood was not brought inside the sanctuary, you should certainly have eaten it in the sanctuary, as I commanded."
And Aaron spoke to Moses, "See, this day they brought their sin offering and their burnt offering before the Lord, and such things have befallen me! Had I eaten sin offering today, would the Lord have approved?" And when Moses heard this, he approved.
