Leviticus 1:3-5

3“If you bring a burnt offering from your cattle, you must offer a male that has no defects. Offer it at the entrance to the tent of meeting so that the Lord will accept you.

4Place your hand on the animal’s head. The burnt offering will be accepted to make peace with the Lord.

5Then slaughter the bull in the Lord’s presence. Aaron’s sons, the priests, will offer the blood. They will throw it against all sides of the altar that is at the entrance to the tent of meeting.
