Editing Mesechtas Beitzah (section)

== Duplicate Mishna ==
The Rebbe asks why it's necessary to write in Tractate Beitzah that one must water the animal before shechita, when this law is already written in Tractate Tamid: "They watered the Tamid with a golden cup," and vice versa. He resolves this with two distinctions:

# The need to write it in Tractate Tamid - because in mundane matters one can do as they wish, even things that aren't necessary, unlike in kodshim where unnecessary work is forbidden. Therefore, one might think this isn't considered part of the service, and thus forbidden on Yom Tov.
# The need to write it in Tractate Beitzah is because specifically with kodshim there is special care that all the meat should go to the mizbeach and all the hide to the kohanim, which is not the case with mundane animals. Also, in the case of a sircha, one shouldn't ruin the animal from being offered on the mizbeach, even though in truth it wasn't attached and one would be needlessly ruining kodshim and destroying its form.
