Leviticus 7:4 ASV

²  In the place where they kill the burnt-offering shall they kill the trespass-offering; and the blood thereof shall he sprinkle upon the altar round about.

³  And he shall offer of it all the fat thereof: the fat tail, and the fat that covereth the inwards,

⁴  and the two kidneys, and the fat that is on them, which is by the loins, and the caul upon the liver, with the kidneys, shall he take away;

⁵  and the priest shall burn them upon the altar for an offering made by fire unto Jehovah: it is a trespass-offering.

⁶  Every male among the priests shall eat thereof: it shall be eaten in a holy place: it is most holy.
