Exodus 29:10-14

10“Bring the young bull to the entrance of the Tabernacle, where Aaron and his sons will lay their hands on its head.

11Then slaughter the bull in the Lord’s presence at the entrance of the Tabernacle.

12Put some of its blood on the horns of the altar with your finger, and pour out the rest at the base of the altar.

13Take all the fat around the internal organs, the long lobe of the liver, and the two kidneys and the fat around them, and burn it all on the altar.

14Then take the rest of the bull, including its hide, meat, and dung, and burn it outside the camp as a sin offering.
