Leviticus 7:3-5

LEB(i) 3 And he must present all of its fat:* the fat tail and the fat that covers the inner parts,* 4 and the two kidneys, and the fat that is on them, which is on the loins, and he must remove the lobe on the liver in addition to the kidneys. 5 And the priest shall turn it into smoke it on the altar as a food offering made by fire for Yahweh; it is a guilt offering.
