Exodus 29:15-30

“You shall also take one ram, and Aaron and his sons shall put their hands on the head of the ram; and you shall kill the ram, and you shall take its blood and sprinkle it all around on the altar. Then you shall cut the ram in pieces, wash its entrails and its legs, and put them with its pieces and with its head. And you shall burn the whole ram on the altar. It is a burnt offering to the LORD; it is a sweet aroma, an offering made by fire to the LORD. “You shall also take the other ram, and Aaron and his sons shall put their hands on the head of the ram. Then you shall kill the ram, and take some of its blood and put it on the tip of the right ear of Aaron and on the tip of the right ear of his sons, on the thumb of their right hand and on the big toe of their right foot, and sprinkle the blood all around on the altar. And you shall take some of the blood that is on the altar, and some of the anointing oil, and sprinkle it on Aaron and on his garments, on his sons and on the garments of his sons with him; and he and his garments shall be hallowed, and his sons and his sons’ garments with him. “Also you shall take the fat of the ram, the fat tail, the fat that covers the entrails, the fatty lobe attached to the liver, the two kidneys and the fat on them, the right thigh (for it is a ram of consecration), one loaf of bread, one cake made with oil, and one wafer from the basket of the unleavened bread that is before the LORD; and you shall put all these in the hands of Aaron and in the hands of his sons, and you shall wave them as a wave offering before the LORD. You shall receive them back from their hands and burn them on the altar as a burnt offering, as a sweet aroma before the LORD. It is an offering made by fire to the LORD. “Then you shall take the breast of the ram of Aaron’s consecration and wave it as a wave offering before the LORD; and it shall be your portion. And from the ram of the consecration you shall consecrate the breast of the wave offering which is waved, and the thigh of the heave offering which is raised, of that which is for Aaron and of that which is for his sons. It shall be from the children of Israel for Aaron and his sons by a statute forever. For it is a heave offering; it shall be a heave offering from the children of Israel from the sacrifices of their peace offerings, that is, their heave offering to the LORD. “And the holy garments of Aaron shall be his sons’ after him, to be anointed in them and to be consecrated in them. That son who becomes priest in his place shall put them on for seven days, when he enters the tabernacle of meeting to minister in the holy place.
