Leviticus 10:12-15

12And Moses said to Aaron and his remaining sons, Eleazar and Ithamar, “Take the grain offering that remains from the food offerings to the LORD and eat it without leaven beside the altar, because it is most holy. 13You shall eat it in a holy place, because it is your share and your sons’ share of the food offerings to the LORD; for this is what I have been commanded.

14And you and your sons and daughters may eat the breast of the wave offering and the thigh of the contribution in a ceremonially clean place, because these portions have been assigned to you and your children from the peace offerings of the sons of Israel. 15They are to bring the thigh of the contribution and the breast of the wave offering, together with the fat portions of the food offerings, to wave as a wave offering before the LORD. It will belong permanently to you and your children, as the LORD has commanded.”
