Leviticus [Pertaining to Levites] 4:7-9

⁸He shall take all the fat of the bull of the sin offering off of it; the fat that covers the innards, and all the fat that is on the innards,

⁹and the two kidneys, and the fat that is on them, which is by the loins, and the cover on the liver, with the kidneys, he shall take away,
