Exodus 29:15-30

“Then take one of the rams. Have Aaron and his sons place their hands on the head of the ram. Slaughter the ram and take its blood and throw it against the Altar, all around. Cut the ram into pieces; wash its innards and legs, then gather the pieces and its head and burn the whole ram on the Altar. It is a Whole-Burnt-Offering to GOD, a pleasant fragrance, an offering by fire to GOD. “Then take the second ram. Have Aaron and his sons place their hands on the ram’s head. Slaughter the ram. Take some of its blood and rub it on Aaron’s right earlobe and on the right earlobes of his sons, on the thumbs of their right hands and on the big toes of their right feet. Sprinkle the rest of the blood against all sides of the Altar. Then take some of the blood that is on the Altar, mix it with some of the anointing oil, and splash it on Aaron and his clothes and on his sons and their clothes so that Aaron and his clothes and his sons and his sons’ clothes will be made holy. “Take the fat from the ram, the fat tail, the fat that covers the innards, the long lobe of the liver, the two kidneys and the fat on them, and the right thigh: this is the ordination ram. Also take one loaf of bread, an oil cake, and a wafer from the breadbasket that is in the presence of GOD. “Place all of these in the open hands of Aaron and his sons who will wave them before GOD, a Wave-Offering. Then take them from their hands and burn them on the Altar with the Whole-Burnt-Offering—a pleasing fragrance before GOD, a gift to GOD. “Now take the breast from Aaron’s ordination ram and wave it before GOD, a Wave-Offering. That will be your portion. “Bless the Wave-Offering breast and the thigh that was held up. These are the parts of the ordination ram that are for Aaron and his sons. Aaron and his sons are always to get this offering from the Israelites; the Israelites are to make this offering regularly from their Peace-Offerings. “Aaron’s sacred garments are to be handed down to his descendants so they can be anointed and ordained in them. The son who succeeds him as priest is to wear them for seven days and enter the Tent of Meeting to minister in the Holy Place.
