Exodus 29:33-37

VIN(i) 33 "They shall eat those things used for their atonement and their ordination and consecration. A layman shall not eat them, because they are holy. 34 »If any of the flesh of ordination or any of the bread remains until morning it should be burned with fire. It should not be eaten because it is holy. 35 "Do to Aaron and to his sons all that I have commanded you. Ordain them for seven days. 36 »Offer a bull as a sin offering for atonement each day. Purify the altar when you make atonement for it. Anoint it to consecrate it. 37 You shall make atonement for the altar for seven days and consecrate it. It will be most holy, and whatever touches it will be holy."
