Leviticus 3:3-5

Darby Translation

³ And he shall present of the sacrifice of peace-offering an offering by fire to Jehovah; the fat that covereth the inwards, and all the fat that is on the inwards,

⁴ and the two kidneys, and the fat that is on them, which is by the flanks, and the net above the liver which he shall take away as far as the kidneys;

⁵ and Aaron's sons shall burn it on the altar upon the burnt-offering which [lieth] on the wood that is upon the fire: [it is] an offering by fire to Jehovah of a sweet odour.
