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, it shall he take away.

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

¹²And if his offering 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 the blood thereof upon the altar round about.
