Exodus 29:19-29:37

Then take the other ram, and let Aaron and his sons lay their hands upon the ram's head. Slaughter the ram, and take some of its blood and put it on the ridge of Aaron's right ear and on the ridges of his sons' right ears, and on the thumbs of their right hands, and on the big toes of their right feet; and dash the rest of the blood against every side of the altar round about. Take some of the blood that is on the altar and some of the anointing oil and sprinkle upon Aaron and his vestments, and also upon his sons and his sons' vestments. Thus shall he and his vestments be holy, as well as his sons and his sons' vestments. You shall take from the ram the fat parts--the broad tail, the fat that covers the entrails, the protuberance on the liver, the two kidneys with the fat on them--and the right thigh; for this is a ram of ordination. Add one flat loaf of bread, one cake of oil bread, and one wafer, from the basket of unleavened bread that is before the Lord. Place all these on the palms of Aaron and his sons, and offer them as an elevation offering before the Lord. Take them from their hands and turn them into smoke upon the altar with the burnt offering, as a pleasing odor before the Lord; it is an offering by fire to the Lord. Then take the breast of Aaron's ram of ordination and offer it as an elevation offering before the Lord; it shall be your portion. You shall consecrate the breast that was offered as an elevation offering and the thigh that was offered as a gift offering from the ram of ordination--from that which was Aaron's and from that which was his sons'--and those parts shall be a due for all time from the Israelites to Aaron and his descendants. For they are a gift; and so shall they be a gift from the Israelites, their gift to the Lord out of their sacrifices of well-being. The sacral vestments of Aaron shall pass on to his sons after him, for them to be anointed and ordained in. He among his sons who becomes priest in his stead, who enters the Tent of Meeting to officiate within the sanctuary, shall wear them seven days. You shall take the ram of ordination and boil its flesh in the sacred precinct; 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. These things shall be eaten only by those for whom expiation was made with them when they were ordained and consecrated; they may not be eaten by a layman, for they are holy. And if any of the flesh of ordination, or any of the bread, is left until morning, you shall put what is left to the fire; it shall not be eaten, for it is holy. Thus you shall do to Aaron and his sons, just as I have commanded you. You shall ordain them through seven days, and each day you shall prepare a bull as a sin offering for expiation; you shall purge the altar by performing purification upon it, and you shall anoint it to consecrate it. Seven days you shall perform purification for the altar to consecrate it, and the altar shall become most holy; whatever touches the altar shall become consecrated.
