Leviticus 10:12-13

¶ And Moses spake unto Aaron, and unto Eleazar and unto Ithamar, his sons that were left, Take the meat 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:

And 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.
