Leviticus 9:18-20

Darby Translation

¹⁸ And he slaughtered the bullock and the ram of the sacrifice of peace-offering which was for the people. And Aaron's sons delivered to him the blood, and he sprinkled it on the altar round about;

¹⁹ and the pieces of fat of the bullock and of the ram, the fat tail and what covers [the inwards], and the kidneys, and the net of the liver;

²⁰ and they put the pieces of fat on the breast-pieces, and he burned the pieces of fat on the altar;
