Leviticus 3:10-13

¹⁰and the two kidneys, and the fat that is upon them, which is by the loins, and the lobe above the liver, which he shall take away by the kidneys.

¹¹And the priest shall make it smoke 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 present it before the LORD.

¹³And he shall lay his hand upon the head of it, and kill it before the tent of meeting; and the sons of Aaron shall dash the blood thereof against the altar round about.
