Leviticus 1:3-5

New Revised Standard Version, Anglicised Catholic Edition

³ If the offering is a burnt-offering from the herd, you shall offer a male without blemish; you shall bring it to the entrance of the tent of meeting, for acceptance in your behalf before the Lord. ⁴ You shall lay your hand on the head of the burnt-offering, and it shall be acceptable in your behalf as atonement for you. ⁵ The bull shall be slaughtered before the Lord; and Aaron’s sons the priests shall offer the blood, dashing the blood against all sides of the altar that is at the entrance of the tent of meeting.
