Leviticus 3:13-15

New Revised Standard Version Catholic Edition

¹³ and lay your hand on its head; it shall be slaughtered before the tent of meeting; and the sons of Aaron shall dash its blood against all sides of the altar. ¹⁴ You shall present as your offering from it, as an offering by fire to the Lord, the fat that covers the entrails, and all the fat that is around the entrails; ¹⁵ the two kidneys with the fat that is on them at the loins, and the appendage of the liver, which you shall remove with the kidneys.
