Leviticus 3:3-5

The Voice

³ From the sacrifice of the peace offerings, you must bring to Me as a fire-offering the fat covering and surrounding the animal’s organs, ⁴ the two kidneys and also the fat on them from the loins, and the lobe of the liver (which will be removed along with the kidneys). ⁵ Aaron’s sons will offer this peace offering on top of the burnt offering on the altar, and the smoke of the sacrifice will rise and be a pleasant aroma to Me.
