Leviticus 1:6

And he shall flay the burnt-offering— He, that is, the offerer, as it is generally thought. Abrabenel asserts, that the owner of the sacrifice laid his hands upon it, killed, flayed, cut it up, and washed the entrails; and then the priest received the blood in a vessel, sprinkled it, put fire on the altar, laid the wood upon the fire, and placed the pieces of the sacrifices upon the wood.
