Leviticus 3:9

‘Then he shall bring near from it all its fat: the fat tail and the fat that covers the entrails,

Then he slaughtered the ox and the ram, the sacrifice of peace offerings which was for the people; and Aaron’s sons handed the blood to him, and he splashed it around on the altar.

As for the portions of fat from the ox and from the ram, the fat tail and the fat covering and the kidneys and the lobe of the liver,

and for the sacrifice of peace offerings, two oxen, five rams, five male goats, five male lambs one year old. This was the offering of Gamaliel the son of Pedahzur.

“And you shall offer your burnt offerings, the flesh and the blood, on the altar of Yahweh your God; and the blood of your sacrifices shall be poured out on the altar of Yahweh your God, and you shall eat the flesh.
