Leviticus 1:3-5

3“ ‘If the offering is a burnt offering from the herd, you are to offer a male without defect. You must present it at the entrance to the tent of meeting so that it will be acceptable to the Lord. 4You are to lay your hand on the head of the burnt offering, and it will be accepted on your behalf to make atonement for you. 5You are to slaughter the young bull before the Lord, and then Aaron’s sons the priests shall bring the blood and splash it against the sides of the altar at the entrance to the tent of meeting.
