Leviticus 10:13-15

13And ye shall eat it in the holy place, because it is thy due, and thy sons’ due, of the sacrifices of the LORD 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 are thy due, and thy sons’ due, which are given out of the sacrifices of peace offerings of the children of Israel. 15The heave shoulder and the wave breast shall they bring with the offerings made by fire of the fat, to wave it for a wave offering before the LORD; and it shall be thine, and thy sons’ with thee, by a statute for ever; as the LORD hath commanded.
