Leviticus 10:20

“Why haven’t you eaten the sin offering in the place of the sanctuary, 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 the LORD?

Behold, its blood was not brought into the inner part of the sanctuary. You certainly should have eaten it in the sanctuary, as I commanded.”

Aaron spoke to Moses, “Behold, today they have offered their sin offering and their burnt offering before the LORD; and such things as these have happened to me. If I had eaten the sin offering today, would it have been pleasing in the LORD’s sight?”
