Leviticus 10:12-14

12And Moses spake unto Aaron, and unto Eleazar and unto Ithamar, his sons that were left, Take the meal offering that remaineth of the offerings of the LORD made by fire, and eat it without leaven beside the altar: for it is most holy:

13and ye shall eat it in a holy place, because it is thy due, and thy sons’ due, of the offerings of the LORD made by fire: for so I am commanded.

14And the wave breast and the heave thigh shall ye eat in a clean place; thou, and thy sons, and thy daughters with thee: for they are given as thy due, and thy sons’ due, out of the sacrifices of the peace offerings of the children of Israel.
