Leviticus 10:12-14

12And Moses spake unto Aaron, and unto Eleazar and unto Ithamar, his sons that were left, Take the grain offering that remaineth of the offerings of Yhwh made by fire, and eat it without leaven beside the altar: for it is most holy: 13And ye shall eat it in the holy place, because it is thy due, and thy sons’ due, of the sacrifices of Yhwh made by fire: for so I am commanded. 14And the wave breast and heave shoulder shall ye eat in a clean place; thou, and thy sons, and thy daughters with thee: for they be thy due, and thy sons’ due, which are given out of the sacrifices of peace offerings of the children of Israel.
