In Exodus 34:21 we read, “Remember the Sabbath Day, to keep it holy. Six days you shall labor and do all your work; but the seventh day is a Sabbath unto the Lord your G‑d. On it you shall not do any manner of work — you, your son, your daughter, your man-servant, your maid-servant, your cattle, and your stranger that is within your gates. For in six days the Lord made heaven and earth, the sea and all that in them is, and rested on the seventh day; wherefore the Lord blessed the Sabbath Day, and hallowed it.”
It’s very clear from this verse that Shabbat is not just for the Jewish people, but for everyone in our houses, animals and people alike, and, most notably for today’s daf, Shabbat is for people we employ.
Today’s daf brings up a question: What if a non-Jewish person does something that would make an area permitted during Shabbat that was not before? What if they “do work” for our benefit out of their own free will? Can we benefit?
To answer this question a principle is is stated:
Rava states to Rav Naḥman from the following baraita: This is the principle: Anything that is permitted for part of Shabbat is permitted for all of Shabbat, and anything that is prohibited for part of Shabbat is prohibited for all of Shabbat, apart from one who renounces his rights in a courtyard, for renunciation can provide an allowance halfway through Shabbat.
The Gemara now explains each element of the baraita: Anything that is permitted for part of Shabbat is permitted for all of Shabbat. For example, if an eiruv was established between two adjacent courtyards that are connected via an opening between them, and that opening was closed up on Shabbat, the eiruv is valid. Alternately, if an eiruv was established between the two courtyards that are connected via a window opening from one to the other, and that window was closed up on Shabbat, the eiruv is valid. As carrying from one courtyard to another was permitted at the beginning of Shabbat, it is permitted throughout Shabbat.
The Gemara comments: The words this is the principle come to include the case of an alleyway whose cross beams or side posts were removed on Shabbat, teaching that one may nonetheless use the alleyway, as it had been permitted at the outset of Shabbat.
Here, we see the causal opening and closing of windows does not change something that was permitted from being permitted. But what about the opposite? What if something was forbidden and then work is done that would have allowed it to be permitted? Can we use it now? Even in the middle of Shabbat?
The Gemara continues its explanation of the baraita: Anything that is prohibited for part of Shabbat is prohibited for all of Shabbat. For example, if there were two houses on two sides of a public domain, which gentiles enclosed with a wall on Shabbat, the enclosed area remains prohibited.
Even though a partition of this kind is considered a proper one with regard to Shabbat domains, it is prohibited to carry objects from either house into the enclosed area.
I find this really interesting in that it places a safe guard around the commandment from Exodus to remember Shabbat, not just for you, but for everyone. Had the rabbis ruled otherwise and permitted this new alleyway to Jewish people, you could see how one might try and make a non-Jew work on Shabbat for personal benefit. (And there are a whole group of people who do this!)
Shabbat, while an institution for Jewish people, is a rule for everyone. Everyone needs a day off, a break. It’s not always easy to take a day off. that’s why it’s commanded. And perhaps it’s hard for employers to give a day off. that’s why it’s commanded. This ruling that prohibits the use of the alleyway, even though the work done by the non-jews would make it permitted, serves as a fence around the law. Our observance of Shabbat should not benefit from others not observing Shabbat. Instead, we should work for a time where everyone has the freedom of one day to reconnect to friends, family, God, and the soul.
