Leviticus 1:3-5

3If 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.

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

5And 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.
