Leviticus 10:12-14

12Then Moses said to Aaron and his remaining sons, Eleazar and Ithamar, “Take what is left of the grain offering after a portion has been presented as a special gift to the Lord, and eat it beside the altar. Make sure it contains no yeast, for it is most holy.

13You must eat it in a sacred place, for it has been given to you and your descendants as your portion of the special gifts presented to the Lord. These are the commands I have been given.

14But the breast and thigh that were lifted up as a special offering may be eaten in any place that is ceremonially clean. These parts have been given to you and your descendants as your portion of the peace offerings presented by the people of Israel.
