Leviticus 3:1-2

Living Bible

3 “When anyone wants to give an offering of thanksgiving to the Lord, he may use either a bull or a cow, but the animal must be entirely without defect if it is to be offered to the Lord! ² The man who brings the animal shall lay his hand upon its head and kill it at the door of the Tabernacle. Then Aaron’s sons shall throw the blood against the sides of the altar
