Leviticus 10:14-15

14But the breast that is waved and the thigh that is contributed you shall eat in a clean place, you and your sons and your daughters with you, for they are given as your due and your sons' due from the sacrifices of the peace offerings of the people of Israel.

15The thigh that is contributed and the breast that is waved they shall bring with the food offerings of the fat pieces to wave for a wave offering before the Lord, and it shall be yours and your sons' with you as a due forever, as the Lord has commanded."
