Hello <i>chevra</i> and thank you for joining as we continue learning together. I just wanted to say a short word before the next set of <i>Mishnayos</i>, which we can group under one idea.

The idea being <i>Ein Shvus Bamikdash</i>. A <i>shvus</i> is typically defined as an <i>issur derabbanan</i>, meaning a prohibition that the <i>chachamim</i> instituted generally related to <i>Shabbos</i>, meaning to say that it's not prohibited by the Torah, it's not an <i>issur de'oraisa</i>, but the <i>chachamim</i> established many <i>gederim</i>, fences around <i>Shabbos</i> and they instituted many <i>issurim</i> that are meant to prevent us from violating <i>Shabbos</i>.

So for instance, one is not allowed to ride on an animal on <i>Shabbos</i>. That is a <i>derabbanan</i>, meaning it's not inherently prohibited <i>assur</i> from the Torah, but the <i>chachamim</i> said that one is not permitted to do that for a variety of reasons.

And there are many of these rules when it comes to <i>Shabbos</i>. Importantly however, while these rules applied outside the <i>Beis Hamikdash</i>, inside the <i>Beis Hamikdash</i>, a number of these fences simply fall away.

So that things that the <i>chachamim</i> forbade on <i>Shabbos</i> everywhere else are actually permitted in the <i>Beis Hamikdash</i>. Similarly, certain rabbinic decrees, certain <i>gezeiros</i> related to <i>tumah</i> and <i>taharah</i> are also set aside in the <i>Beis Hamikdash</i> as well.

Now the question of course is, why is that the case? And the answer is because these fences were built to keep ordinary people from stumbling into a Torah violation, meaning it is very easy to violate an <i>issur de'oraisa</i> and therefore the <i>chachamim</i> instituted these things in order to prevent you from getting even close to violating an <i>issur de'oraisa</i>.

But in the <i>Beis Hamikdash</i>, where the <i>kohanim</i> were serving under the eye of the <i>Sanhedrin</i>, the <i>chachamim</i> trusted that everyone would stay careful. Therefore where that care can be assured, the extra fences aren't needed.

So as we learn these <i>mishnayos</i> in <i>Eduyos</i> and <i>Keilim</i> and across the tenth <i>perek</i> of <i>Eiruvin</i>, hold onto the single thread that in the <i>Beis Hamikdash</i>, it's the one place where the <i>chachamim's</i> own <i>chumras</i> can give way because there no one will stumble. And with that I wish you continuing <i>hatzlacha</i> in your learning.
