Leviticus 3:3-5

New Living Translation

³ The priest must present part of this peace offering as a special gift to the Lord. This includes all the fat around the internal organs, ⁴ the two kidneys and the fat around them near the loins, and the long lobe of the liver. These must be removed with the kidneys, ⁵ and Aaron’s sons will burn them on top of the burnt offering on the wood burning on the altar. It is a special gift, a pleasing aroma to the Lord.
