Leviticus 3:3-4

³'And he hath brought near from the sacrifice of the peace-offerings a fire-offering to Jehovah, the fat which is covering the inwards, and all the fat which is on the inwards,

⁴and the two kidneys, and the fat which is on them, which is on the flanks, and the redundance above the liver, (beside the kidneys he doth turn it aside),
