Exodus 29:31-33

New Revised Standard Version Catholic Edition

³¹ You shall take the ram of ordination, and boil its flesh in a holy place; ³² and Aaron and his sons shall eat the flesh of the ram and the bread that is in the basket, at the entrance of the tent of meeting. ³³ They themselves shall eat the food by which atonement is made, to ordain and consecrate them, but no one else shall eat of them, because they are holy.
