Leviticus 3:3-5

New Revised Standard Version Catholic Edition

³ You shall offer from the sacrifice of well-being, as an offering by fire to the Lord, the fat that covers the entrails and all the fat that is around the entrails; ⁴ 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. ⁵ Then Aaron’s sons shall turn these into smoke on the altar, with the burnt offering that is on the wood on the fire, as an offering by fire of pleasing odor to the Lord.
