The Offering of the Lambs and the Bread of Atonement

Aaron and his sons shall eat the flesh of the ram and the bread that is in the basket at the door of the tent of meeting. They shall eat those things with which atonement was made to ordain and consecrate them. But an outsider shall not eat of them, because they are holy. And if any of the flesh for the ordination or of the bread remain until the morning, then you shall burn the remainder with fire. It shall be a continual burnt offering throughout your generations. I will dwell among the sons of israel; i will be their god. The book of leviticus, chapter 21, the holiness of priests.
