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.

⁶ And if his offering for a sacrifice of peace-offering to Jehovah be of small cattle, male or female, he shall present it without blemish.
