Leviticus 1:3-5

3If his offering is a burnt offering from the herd, he shall offer a male without blemish; he shall offer it at the doorway of the Tent of Meeting so that he may be accepted before the Lord.

4He shall lay his hand on the head of the burnt offering [transferring symbolically his guilt to the sacrifice], that it may be accepted for him to make atonement on his behalf.

5He shall kill the young bull before the Lord; and Aaron’s sons the priests shall present the blood and sprinkle the blood around on the altar that is at the doorway of the Tent of Meeting.
