Exodus 29:10-25

“You are to bring the bull to the front of the tent of meeting, and Aaron and his sons must lay their hands on the bull’s head.  Slaughter the bull before the Lord at the entrance to the tent of meeting. Take some of the bull’s blood and apply it to the horns  of the altar with your finger; then pour out all the rest of the blood at the base of the altar. Take all the fat  that covers the entrails, the fatty lobe of the liver, and the two kidneys with the fat on them, and burn them on the altar. But burn the bull’s flesh, its hide, and its waste outside the camp;  it is a sin offering. “Take one ram, and Aaron and his sons are to lay their hands on the ram’s head.  You are to slaughter the ram, take its blood, and splatter it on all sides of the altar. Cut the ram into pieces. Wash its entrails and legs, and place them with its head and its pieces on the altar. Then 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 are to take the second ram, and Aaron and his sons must lay their hands on the ram’s head.  Slaughter the ram, take some of its blood, and put it on Aaron’s right earlobe, on his sons’ right earlobes, on the thumbs of their right hands, and on the big toes of their right feet. Splatter the remaining blood on all sides of the altar. Take some of the blood that is on the altar and some of the anointing oil,  and sprinkle them on Aaron and his garments, as well as on his sons and their garments. So he and his garments will be holy, as well as his sons and their garments. “Take the fat from the ram, the fat tail, the fat covering the entrails, the fatty lobe of the liver, the two kidneys and the fat on them, and the right thigh (since this is a ram for ordination  ); take one loaf of bread, one cake of bread made with oil, and one wafer from the basket of unleavened bread that is before the Lord; and put all of them in the hands of Aaron and his  sons and present them as a presentation offering before the Lord.  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.
