Leviticus 10:12-14

12Then Moses said to Aaron, and to his surviving sons, Eleazar and Ithamar, “Take the grain offering that is left over from the offerings by fire to the Lord, and eat it unleavened beside the altar, for it is most holy.

13You shall eat it in a holy place, because it is your portion and your sons’ portion, from the offerings by fire to the Lord; for so I have been commanded.

14But the breast of the wave offering and the thigh of the heave offering you may eat in a clean place, you and your sons and daughters with you; for the breast and the thigh are your portion and your sons’ portion, given out of the sacrifices of the peace offerings of the Israelites.
