Leviticus 9:2-13

²and he said unto Aaron, Take thee a young calf for a sin offering, and a ram for a burnt offering, without blemish, and offer them before the Lord.

³And unto the children of Israel thou shalt speak, saying, Take ye a kid of the goats for a sin offering; and a calf and a lamb, both of the first year, without blemish, for a burnt offering;

⁴also a bullock and a ram for peace offerings, to sacrifice before the Lord; and a meat offering mingled with oil: for to day the Lord will appear unto you.

⁵And they brought that which Moses commanded before the tabernacle of the congregation: and all the congregation drew near and stood before the Lord.

⁶And Moses said, This is the thing which the Lord commanded that ye should do: and the glory of the Lord shall appear unto you.

⁷And Moses said unto Aaron, Go unto the altar, and offer thy sin offering, and thy burnt offering, and make an atonement for thyself, and for the people: and offer the offering of the people, and make an atonement for them; as the Lord commanded.

⁸Aaron therefore went unto the altar, and slew the calf of the sin offering, which was for himself.

⁹And the sons of Aaron brought the blood unto him: and he dipt his finger in the blood, and put it upon the horns of the altar, and poured out the blood at the bottom of the altar:

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

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

¹²And he slew the burnt offering; and Aaron’s sons presented unto him the blood, which he sprinkled round about upon the altar.

¹³And they presented the burnt offering unto him, with the pieces thereof, and the head: and he burnt them upon the altar.
