Leviticus 7:3-5

Lexham English Bible

³ And he must present all of its fat:^[a] the fat tail and the fat that covers the inner parts,^{[b] 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.
