Leviticus 3:3-5

Young's Literal Translation

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,

⁴ and 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),

⁵ and sons of Aaron have made it a perfume on the altar, on the burnt-offering which [is] on the wood, which [is] on the fire -- a fire-offering of sweet fragrance to Jehovah.
