Leviticus 10:12-14

12Then Moses spoke to Aaron and to Eleazar and Ithamar, his remaining sons, “Take the grain offering which remains from the gifts of the Lord and eat it unleavened beside the altar, for it is most holy.

13You must eat it in a holy place because it is your allotted portion and the allotted portion of your sons from the gifts of the Lord, for this is what I have been commanded.

14Also, the breast of the wave offering and the thigh of the contribution offering you must eat in a ceremonially clean place, you and your sons and daughters with you, for they have been given as your allotted portion and the allotted portion of your sons from the peace offering sacrifices of the Israelites.
