Leviticus 10:13-15

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.

15You must lift up the thigh and breast as a special offering to the Lord, along with the fat of the special gifts. These parts will belong to you and your descendants as your permanent right, just as the Lord has commanded.”
