Leviticus 7:2-4

Living Bible

² “The sacrificial animal shall be killed at the place where the burnt offering sacrifices are slain, and its blood shall be sprinkled back and forth upon the altar. ³ The priest will offer upon the altar all its fat, including the tail, the fat that covers the insides, ⁴ the two kidneys and the loin fat, and the gall bladder—all shall be set aside for sacrificing.
