Exodus 29:12-19

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.
