Leviticus 4:7-9

New Century Version

⁷ The priest must also put some of the blood on the corners of the altar of incense that stands before the Lord in the Meeting Tent. The rest of the blood he must pour out at the bottom of the altar of burnt offering, which is at the entrance of the Meeting Tent. ⁸ He must remove all the fat from the bull of the sin offering—the fat on and around the inner organs, ⁹ both kidneys with the fat that is on them near the lower back muscle, and the best part of the liver which he will remove with the kidneys.
