Leviticus 10:12; Leviticus 10:17

12 Moses spoke to Aaron and to Eleazar and Ithamar, his surviving sons: "Take the grain offering that is left of the LORD's food offerings, and eat it unleavened beside the altar, for it is most holy.

17 "Why have you not eaten the sin offering in the place of the sanctuary, since it is a thing most holy and has been given to you that you may bear the iniquity of the congregation, to make atonement for them before the LORD?
