Leviticus 1:3-9

3"If his offering is a burnt offering from the herd, he shall offer a male without blemish. He shall bring it to the entrance of the tent of meeting, that he may be accepted before the Lord.

4He shall lay his hand on the head of the burnt offering, and it shall be accepted for him to make atonement for him.

5Then he shall kill the bull before the Lord, and Aaron's sons the priests shall bring the blood and throw the blood against the sides of the altar that is at the entrance of the tent of meeting.

6Then he shall flay the burnt offering and cut it into pieces,

7and the sons of Aaron the priest shall put fire on the altar and arrange wood on the fire.

8And Aaron's sons the priests shall arrange the pieces, the head, and the fat, on the wood that is on the fire on the altar;

9but its entrails and its legs he shall wash with water. And the priest shall burn all of it on the altar, as a burnt offering, a food offering with a pleasing aroma to the Lord.
