Leviticus 1:3-7

If your offering is a burnt offering from a herd of cattle, you must offer a male without any defects. Bring it to the entrance of the Tent of Meeting so it can be accepted before the Lord.

Put your hand on the head of the burnt offering, so it can be accepted on your behalf to make you right.

You are to kill the bull in the Lord's presence, and Aaron's sons, the priests, are to take the blood and sprinkle it on all sides of the altar at the entrance to the Tent of Meeting.

Then you are to skin the burnt offering and cut it into pieces.

The sons of Aaron the priest shall start a fire on the altar and put wood on it.
