Leviticus 7:2-5

2In 1the place where they slaughter the burnt offering they are to slaughter the guilt offering, and the priest shall sprinkle its blood around on the altar.

3Then he shall offer from it all its fat: the 2fat tail and the fat that covers the entrails,

4and the two kidneys with the fat that is on them, which is on the loins; and he shall remove the lobe on the liver 3with the kidneys.

5The priest shall offer them up in smoke on the altar as an offering by fire to the Lord; it is a guilt offering.
