Leviticus 1:6

3 If his offering be a burnt sacrifice of the herd, let him offer a male without blemish: he shall offer it of his own voluntary will at the door of the tabernacle of the congregation before the LORD.

4 And he shall put his hand upon the head of the burnt offering; and it shall be accepted for him to make atonement for him.

5 And he shall kill the bullock before the LORD: and the priests, Aaron's sons, shall bring the blood, and sprinkle the blood round about upon the altar that is by the door of the tabernacle of the congregation.

6 And he shall flay the burnt offering, and cut it into his pieces.

7 And the sons of Aaron the priest shall put fire upon the altar, and lay the wood in order upon the fire:

8 And the priests, Aaron's sons, shall lay the parts, the head, and the fat, in order upon the wood that is on the fire which is upon the altar:

9 But his inwards and his legs shall he wash in water: and the priest shall burn all on the altar, to be a burnt sacrifice, an offering made by fire, of a sweet savour unto the LORD.
