Leviticus 9:11

8 So Aaron drew near unto the altar, and slew the calf of the sin-offering, which was for himself.

9 And the sons of Aaron presented the blood unto him; and he dipped his finger in the blood, and put it upon the horns of the altar, and poured out the blood at the base of the altar:

10 but the fat, and the kidneys, and the caul from the liver of the sin-offering, he burnt upon the altar; as Jehovah commanded Moses.

11 And the flesh and the skin he burnt with fire without the camp.

12 And he slew the burnt-offering; and Aaron`s sons delivered unto him the blood, and he sprinkled it upon the altar round about.

13 And they delivered the burnt-offering unto him, piece by piece, and the head: and he burnt them upon the altar.

14 And he washed the inwards and the legs, and burnt them upon the burnt-offering on the altar.
