Leviticus 3:4-6

King James Version

⁴ And the two kidneys, and the fat that is on them, which is by the flanks, and the caul above the liver, with the kidneys, it shall he take away.

⁵ And Aaron's sons shall burn it on the altar upon the burnt sacrifice, which is upon the wood that is on the fire: it is an offering made by fire, of a sweet savour unto the Lord.

⁶ And if his offering for a sacrifice of peace offering unto the Lord be of the flock; male or female, he shall offer it without blemish.
