Leviticus 3:13-15

¹³He shall lay his hand on its head, and kill it before the Tent of Meeting; and the sons of Aaron shall sprinkle its blood around on the altar.

¹⁴He shall offer from it as his offering, an offering made by fire to the LORD; the fat that covers the innards, and all the fat that is on the innards,

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