Leviticus 3:10-13

¹⁰And the two kidneys, and the fat that is upon them, which is by the flanks, and the caul above the liver, with the kidneys, that shall he take away.

¹¹And the priest shall burn it upon the altar: it is the food of the offering made by fire to the LORD.

¹²And if his offering shall be a goat, then he shall offer it before the LORD.

¹³And he shall lay his hand upon the head of it, and kill it before the tabernacle of the congregation: and the sons of Aaron shall sprinkle its blood upon the altar round about.
