Leviticus 7:3-5

Tree of Life Version

³ He shall offer all of its fat, the fat tail and the fat that covers the innards, ⁴ along with the two kidneys and the fat that is on them, which is by the loins, plus the cover on the liver that he is to remove with the kidneys. ⁵ Then the kohen shall burn them up as smoke on the altar for an offering made by fire to Adonai. It is a trespass offering.
