Leviticus 1:3-6

If his offering is a burnt offering from the herd, he shall offer it, a male without defect; he shall offer it at the doorway of the tent of meeting, that he may be accepted before the LORD. He shall lay his hand on the head of the burnt offering, that it may be accepted for him to make atonement on his behalf. He shall slay the young bull before the LORD; and Aaron’s sons the priests shall offer up the blood and sprinkle the blood around on the altar that is at the doorway of the tent of meeting. He shall then skin the burnt offering and cut it into its pieces.
