Leviticus 9:10-14

The fat and the kidneys and the lobe of the liver of the sin offering he then offered up in smoke on the altar, just as the Lord had commanded Moses.

The flesh and the hide, however, he burned with fire outside the camp.

Then he slaughtered the burnt offering; and Aaron’s sons brought the blood to him, and he sprinkled it around on the altar.

They brought the burnt offering to him in pieces, with the head, and he offered them up in smoke on the altar.

He also washed the entrails and the legs, and offered them up in smoke with the burnt offering on the altar.
