Leviticus 10:12-15

12Then Moses spoke to Aaron, and to his surviving sons, 1Eleazar and Ithamar, “2Take the grain offering that is left over from the Lord’s offerings by fire and eat it as unleavened bread beside the altar, for it is most holy. 13You shall eat it in a holy place, because it is your allotted portion and your sons’ allotted portion from the Lord’s offerings by fire; for so I have been commanded. 143The breast of the wave offering, however, and the thigh of the offering you may eat in a clean place, you and your sons and your daughters with you; for they have been given as your allotted portion and your sons’ allotted portion from the sacrifices of the peace offerings of the sons of Israel. 15They shall bring 4the thigh offered by lifting up and the breast offered by waving, along with the offerings by fire of the portions of fat, to present as a wave offering before the Lord; so it shall be a thing perpetually due you and your sons with you, just as the Lord has commanded.”
