Leviticus 7:4 WEB

²  In the place where they kill the burnt offering, he shall kill the trespass offering; and its blood he shall sprinkle on the altar round about.

³  He shall offer all of its fat: the fat tail, and the fat that covers the innards,

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

⁵  and the priest shall burn them on the altar for an offering made by fire to Yahweh: it is a trespass offering.

⁶  Every male among the priests may eat of it. It shall be eaten in a holy place. It is most holy.
