Two Logs the Layman's Knife and the Lamb in Six

It is taught: Rabbi Shimon ben Yohai says: from where do we learn that the afternoon daily offering requires two logs of wood, brought by two priests? As it is said, "And they shall arrange wood upon the fire" (Leviticus 1:7). If this verse is not needed for the morning daily offering, since it is written, "and the priest shall burn wood upon it" (Leviticus 6:5), apply it to the matter of the afternoon daily offering. And say that both this and that refer to the morning daily offering, for the Merciful One said: do it and then do it again. If so, let the verse say "and he shall burn" and "and they shall burn," or alternatively "and he shall arrange" and "and they shall arrange." What is the meaning of "and he shall burn" and "and they shall arrange"? As we said. From where that flaying and cutting are valid when done by a layman? As it is said, "And the sons of Aaron the priests shall arrange the pieces." Now since from the receiving of the blood onward it is the commandment of the priesthood, why do I need "and they shall arrange"? To exclude flaying and cutting [from the requirement of priesthood]. "And they shall arrange" - two; "the sons of Aaron" - two; "the priests" - two; we have learned that the lamb requires six. This troubled Rabbi Eliezer: this is written concerning the lamb, but a bull of the herd should require twenty-four. And it sat well with him: "upon the wood that is upon the fire that is upon the altar" - which is the thing about which "wood, fire, and altar" are all written? You must say: this is the lamb.
