Leviticus 3:10-13

¹⁰and the two kidneys and the fat that is with them, which is by the loins, and the lobe of the liver, with the kidneys—he will remove all of this.

¹¹Then the priest will burn it all on the altar as a burnt offering of food to Yahweh.

¹²If the man's offering is a goat, then he will offer it before Yahweh.

¹³He must lay his hand on the head of the goat and kill it before the tent of meeting. Then the sons of Aaron will sprinkle its blood on the sides of the altar.
