Exodus 29:15-30

“Then you shall take one of the rams, and Aaron and his sons shall lay their hands on the head of the ram, and you shall kill the ram and shall take its blood and throw it against the sides of the altar. Then you shall cut the ram into pieces, and wash its entrails and its legs, and put them with its pieces and its head, and burn the whole ram on the altar. It is a burnt offering to the LORD. It is a pleasing aroma, a food offering to the LORD. “You shall take the other ram, and Aaron and his sons shall lay their hands on the head of the ram, and you shall kill the ram and take part of its blood and put it on the tip of the right ear of Aaron and on the tips of the right ears of his sons, and on the thumbs of their right hands and on the great toes of their right feet, and throw the rest of the blood against the sides of the altar. Then you shall take part of the blood that is on the altar, and of the anointing oil, and sprinkle it on Aaron and his garments, and on his sons and his sons’ garments with him. He and his garments shall be holy, and his sons and his sons’ garments with him. “You shall also take the fat from the ram and the fat tail and the fat that covers the entrails, and the long lobe of the liver and the two kidneys with the fat that is on them, and the right thigh (for it is a ram of ordination), and one loaf of bread and one cake of bread made with oil, and one wafer out of the basket of unleavened bread that is before the LORD. You shall put all these on the palms of Aaron and on the palms of his sons, and wave them for a wave offering before the LORD. Then you shall take them from their hands and burn them on the altar on top of the burnt offering, as a pleasing aroma before the LORD. It is a food offering to the LORD. “You shall take the breast of the ram of Aaron’s ordination and wave it for a wave offering before the LORD, and it shall be your portion. And you shall consecrate the breast of the wave offering that is waved and the thigh of the priests’ portion that is contributed from the ram of ordination, from what was Aaron’s and his sons’. It shall be for Aaron and his sons as a perpetual due from the people of Israel, for it is a contribution. It shall be a contribution from the people of Israel from their peace offerings, their contribution to the LORD. “The holy garments of Aaron shall be for his sons after him; they shall be anointed in them and ordained in them. The son who succeeds him as priest, who comes into the tent of meeting to minister in the Holy Place, shall wear them seven days.
