Leviticus 4:8-10

New Revised Standard Version Catholic Edition

⁸ He shall remove all the fat from the bull of sin offering: the fat that covers the entrails and all the fat that is around the entrails; ⁹ the two kidneys with the fat that is on them at the loins; and the appendage of the liver, which he shall remove with the kidneys, ¹⁰ just as these are removed from the ox of the sacrifice of well-being. The priest shall turn them into smoke upon the altar of burnt offering.
