Leviticus 7:34-36

New Revised Standard Version Catholic Edition

³⁴ For I have taken the breast of the elevation offering, and the thigh that is offered, from the people of Israel, from their sacrifices of well-being, and have given them to Aaron the priest and to his sons, as a perpetual due from the people of Israel. ³⁵ This is the portion allotted to Aaron and to his sons from the offerings made by fire to the Lord, once they have been brought forward to serve the Lord as priests; ³⁶ these the Lord commanded to be given them, when he anointed them, as a perpetual due from the people of Israel throughout their generations.
