3If one’s offering is a burnt offering from the herd, he is to present an unblemished male. He must bring it to the entrance to the Tent of Meeting for its acceptance before the LORD.
4He is to lay his hand on the head of the burnt offering, so it can be accepted on his behalf to make atonement for him.
5And he shall slaughter the young bull before the LORD, and Aaron’s sons the priests are to present the blood and sprinkle it on all sides of the altar at the entrance to the Tent of Meeting.
— Leviticus 1:3-5
