LEVITICUS 3:13-15

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 sprinkle the blood thereof upon the altar round about.

¹⁴And he shall offer thereof his oblation, even an offering made by fire unto the LORD; the fat that covereth the inwards, and all the fat that is upon the inwards,

¹⁵and the two kidneys, and the fat that is upon them, which is by the loins, and the caul upon the liver, with the kidneys, shall he take away.
