Exodus 29:12-19

ISV(i) 12 Take some of the blood of the bull, put it on the horns of the altar with your finger, and pour out the rest of the blood at the base of the altar. 13 You are to take all the fat that covers the entrails, the lobe of the liver, the two kidneys, and the fat that is on them and send them up in smoke on the altar. 14 You are to burn the flesh of the bull, its hide, and its refuse with fire outside the camp. It is a sin offering.
15 “You are to take one of the rams, and Aaron and his sons shall lay their hands on its head. 16 Then you are to slaughter the ram, take its blood, and scatter it around the altar. 17 You are to cut the ram into pieces, wash its entrails and legs, put them on the altar along with the pieces and its head, 18 and send up the whole ram in smoke on the altar. It is a burnt offering to the LORD; it’s a soothing aroma, an offering by fire to the LORD.
19 “You are to take the other ram, and Aaron and his sons shall lay their hands on the head of the ram.
