Leviticus 7:34-36

Revised Standard Version

³⁴ For the breast that is waved and the thigh that is offered I have taken from the people of Israel, out of the sacrifices of their peace offerings, 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 of Aaron and of his sons from the offerings made by fire to the Lord, consecrated to them on the day they were presented to serve as priests of the Lord; ³⁶ the Lord commanded this to be given them by the people of Israel, on the day that they were anointed; it is a perpetual due throughout their generations.”
