Leviticus 10:12-13

And Moses spoke to Aaron, and to Eleazar and Ithamar, his sons that were left: Take the sacrifice that is remaining of the oblation of the Lord, and eat it without leaven beside the altar, because it is holy of holies.

And you shall eat it in a holy place: which is given to thee and thy sons of the oblations of the Lord, as it hath been commanded me.
