Shabbos shaboson - menuchas margoah what is different about menuchas arai vs. Margoah?
'os' a sign of how cherished we are to Hashem - Rashi - you rest on My day of rest. the os of Hashem's love is not the fact that he gave us a day off, rather the choice of which day. Why on earth would it be a DIFFERENT day?! - there already existed this day from 6 days of creation, why choose tuesday over shabbos?!!! How does this show special love?
most partnershops are created with the common goal to run a company to produce money. the 2 partners each take a shift to fill in for each other & the goal is constantly fulfilled. however there may be a partnership in which the purpose was just have a partnership in one unifying entity together. If one partner does both jobs to be able to join his partner for a vacation, that is a clear sign that the goal is the unity not the company.
if our day 'off' would be on G-d's work day, & vice versa, we wouldn't see the day off as a partnership of love rather a business partnership. But Hashem says let's squeeze all the work into 6 days so we can take the day off TOGETHER.
Not menuchas arai, - a need to take a break, rather an intentional designated day to truly vacation TOGETHER with Hashem. Since the goal of the mishkan was to set up the 'accomodations' for this togetherness, we'd have thought its docheh shabbos. However Hashem tells us that on Shabbos we are on such a level of closeness that that the need for accomodations is less. - similar to kodem chet eigel in which Hashem would dwell in the heart of each jew without a designated building.
