There are certain areas in our lives that call for special attention and
should have particular honor bestowed on them, like the Shabbos and Holy
Days. For not only are we to honor them with deep devotion and satisfaction,
we’re also to pay homage to them with our finest clothes, dishes, and the
like. And the pious would pay particular and loving attention to those details.
(Don't forget that our Tradition asks us to consciously celebrate those
times with good food, drink, and other accouterments. For, being pious from
a Jewish perspective doesn’t simply charge one with taking stringencies upon
him or herself; it requires one to surrender his or her human longings and
penchants to G-d’s will. The point is that on Shabbos and the Holy Days that
means enjoying good food, drink, relation, and more.)
There are many such ways to honor the Shabbos in fact, but overall it comes
down to "doing anything that would underscore the importance of the
Shabbos". As such, aside from serving your best dishes on your finest china,
wearing your best clothes and the like, you'd also be expected to side-step
your own honor and to do your own part to show respect for the Shabbos.
And so we're taught that illustrious and upstanding figures did all sorts of
menial labor for the glory of the Shabbos.
"Rabbi Abbahu would sit on a stool of ivory and stoke the fire (to be used
on the Shabbos), for example; Rav Saffra would singe the head of a cow for
the (Shabbos) meal; Rava would salt carp (beforehand); Rav Hunah would light
a fire (beforehand); Rav Papa would ready the wicks (for the Shabbos
lights); Rav Chisda would shred beets (for the meals); Rabbah and Rav Yoseph
would chop wood (for the fire); and Rav Nachman would carry things in and
out on his shoulders (that would be needed for the Shabbos); and that "Rav
Annan would purposefully dress in over-alls on Friday... so as to make it
clear on the Shabbos that he was dressed in fine clothing (in its honor)"
We’re to follow their lead and contribute to it as well, thinking more of
the honor of the Shabbos than of our own.
