Leviticus 8:22-29
He brought forward the second ram, the ram of ordination. Aaron and his sons laid their hands upon the ram's head, and it was slaughtered. Moses took some of its blood and put it on the ridge of Aaron's right ear, and on the thumb of his right hand, and on the big toe of his right foot. Moses then brought forward the sons of Aaron, and put some of the blood on the ridges of their right ears, and on the thumbs of their right hands, and on the big toes of their right feet; and the rest of the blood Moses dashed against every side of the altar.
He took the fat--the broad tail, all the fat about the entrails, the protuberance of the liver, and the two kidneys and their fat--and the right thigh. From the basket of unleavened bread that was before the Lord, he took one cake of unleavened bread, one cake of oil bread, and one wafer, and placed them on the fat parts and on the right thigh. He placed all these on the palms of Aaron and on the palms of his sons, and elevated them as an elevation offering before the Lord.
Then Moses took them from their hands and turned them into smoke on the altar with the burnt offering. This was an ordination offering for a pleasing odor; it was an offering by fire to the Lord. Moses took the breast and elevated it as an elevation offering before the Lord; it was Moses' portion of the ram of ordination--as the Lord had commanded Moses.
