Exodus 29:15-30

“Take one of the rams, and Aaron and his sons shall lay their hands on its head. Slaughter it and take the blood and splash it against the sides of the altar. Cut the ram into pieces and wash the internal organs and the legs, putting them with the head and the other pieces. Then burn the entire ram on the altar. It is a burnt offering to the LORD, a pleasing aroma, a food offering presented to the LORD. “Take the other ram, and Aaron and his sons shall lay their hands on its head. Slaughter it, take some of its blood and put it on the lobes of the right ears of Aaron and his sons, on the thumbs of their right hands, and on the big toes of their right feet. Then splash blood against the sides of the altar. And take some blood from the altar and some of the anointing oil and sprinkle it on Aaron and his garments and on his sons and their garments. Then he and his sons and their garments will be consecrated. “Take from this ram the fat, the fat tail, the fat on the internal organs, the long lobe of the liver, both kidneys with the fat on them, and the right thigh. (This is the ram for the ordination.) From the basket of bread made without yeast, which is before the LORD, take one round loaf, one thick loaf with olive oil mixed in, and one thin loaf. Put all these in the hands of Aaron and his sons and have them wave them before the LORD as a wave offering. Then take them from their hands and burn them on the altar along with the burnt offering for a pleasing aroma to the LORD, a food offering presented to the LORD. After you take the breast of the ram for Aaron’s ordination, wave it before the LORD as a wave offering, and it will be your share. “Consecrate those parts of the ordination ram that belong to Aaron and his sons: the breast that was waved and the thigh that was presented. This is always to be the perpetual share from the Israelites for Aaron and his sons. It is the contribution the Israelites are to make to the LORD from their fellowship offerings. “Aaron’s sacred garments will belong to his descendants so that they can be anointed and ordained in them. The son who succeeds him as priest and comes to the tent of meeting to minister in the Holy Place is to wear them seven days.
