Leviticus 3:9-11

The Voice

⁹ From the peace offering, you must bring to Me as a fire-offering its fat, the tail (which is to be cut off near the backbone), the fat covering and surrounding the organs, ¹⁰ the two kidneys and the fat on them from the loins, and the lobe of the liver (which must be removed along with the kidneys). ¹¹ The priest will then offer all these on the altar as a fire-offering to Me.
