Leviticus 3:10-13

¹⁰and both the kidneys and the fat that is upon them, and that which is on the thighs, and the caul which is on the liver with the kidneys,

¹¹the priest shall offer these on the altar: it is a sacrifice of sweet savor, a burnt offering to the Lord.

¹²And if his offering be of the goats, then shall he bring it before the Lord.

¹³And he shall lay his hands on its head; and they shall kill it before the Lord by the doors of the tabernacle of witness; and the priests the sons of Aaron shall pour out the blood on the altar round about.
