Leviticus 4:7-9

New International Version - UK

⁷ The priest shall then put some of the blood on the horns of the altar of fragrant incense that is before the Lord in the tent of meeting. The rest of the bull’s blood he shall pour out at the base of the altar of burnt offering at the entrance to the tent of meeting. ⁸ He shall remove all the fat from the bull of the sin offering – all the fat that is connected to the internal organs, ⁹ both kidneys with the fat on them near the loins, and the long lobe of the liver, which he will remove with the kidneys –
