Leviticus 7:2-4

New Revised Standard Version Catholic Edition

² at the spot where the burnt offering is slaughtered, they shall slaughter the guilt offering, and its blood shall be dashed against all sides of the altar. ³ All its fat shall be offered: the broad tail, the fat that covers the entrails, ⁴ the two kidneys with the fat that is on them at the loins, and the appendage of the liver, which shall be removed with the kidneys.
