Leviticus 3:6

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 savor 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.

⁷  If he offer a lamb for his offering, then shall he offer it before the LORD.

⁸  And he shall lay his hand upon the head of his offering, and kill it before the tabernacle of the congregation: and Aaron's sons shall sprinkle the blood thereof round about upon the altar.
