Leviticus 7:3-5

New Revised Standard Version, Anglicised

³ All its fat shall be offered: the broad tail, the fat that covers the entrails, ⁴ the two kidneys with the fat that is on them at the loins, and the appendage of the liver, which shall be removed with the kidneys. ⁵ The priest shall turn them into smoke on the altar as an offering by fire to the Lord; it is a guilt-offering.
