Leviticus 3:2-4

New Revised Standard Version, Anglicised Catholic Edition

² You shall lay your hand on the head of the offering and slaughter it at the entrance of the tent of meeting; and Aaron’s sons the priests shall dash the blood against all sides of the altar. 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.
