Leviticus 3:14-16

¹⁴The man will offer his sacrifice made by fire to Yahweh. He will remove the fat that covers the inner parts, and all the fat near the inner parts.

¹⁵He will also remove the two kidneys and the fat that is with them, which is by the loins, and the lobe of the liver with the kidneys.

¹⁶The priest will burn all that on the altar as a burnt offering of food, to produce a sweet aroma. All the fat belongs to Yahweh.
