Leviticus 1:3-5

‘If his offering is a burnt sacrifice of the herd, let him offer a male without blemish; he shall offer it of his own free will at the door of the tabernacle of meeting before the LORD. Then he shall put his hand on the head of the burnt offering, and it will be accepted on his behalf to make atonement for him. He shall kill the bull before the LORD; and the priests, Aaron’s sons, shall bring the blood and sprinkle the blood all around on the altar that is by the door of the tabernacle of meeting.
