Six Days of Work and the Many Faces of Forbidden Labor

"Six days shall work be done" (Exodus 35:2). This is what Rabbi Ishmael says: one verse says "Six days shall work be done," and another verse says "Six days you shall labor and do all your work" (Exodus 20:9). How are these two verses upheld? When Israel does the will of the Omnipresent, their work is done by others, as it says "And strangers shall stand and feed your flocks" (Isaiah 61:5); and when Israel does not do the will of the Omnipresent, their work is done by themselves, and not only that, but even the work of others is done by them, as it says "And you shall serve your enemies whom the LORD shall send against you" (Deuteronomy 28:48). "And the seventh day shall be holy to you" (Exodus 35:2). Why is this said? So that the priests should not say: since we are permitted in the Temple, we are permitted within the borders. Therefore Scripture teaches "the seventh day shall be holy to you" - holy to you, but for the Temple it is a weekday. "A Sabbath of solemn rest to the LORD" - it is handed over to the Name, not to the court. "Whoever does work on it shall be put to death" - on it, but not on it and on its fellow. If one wrote two letters, one on the Sabbath and one on the Day of Atonement, or wove two threads, one on the Sabbath and one on the Day of Atonement, I might hear he is liable for each separately; therefore Scripture teaches "Whoever does work on it shall be put to death" - on it, but not on it and on its fellow. Likewise, if the Sabbath and the Day of Atonement fall one after the other, and one did work at twilight between them, one might think he is liable; therefore Scripture teaches "Whoever does work on it" - until the day is fixed. I have only the principal labors and their derivatives, which are forbidden; from where do I know to forbid a rabbinic rest-measure? Scripture teaches "any work" (Exodus 20:10). One might think they are liable to a sin offering for violating a rabbinic rest-measure; therefore Scripture teaches "work" - for the defined labor they are liable, but they are not liable for a rabbinic rest-measure. From where do we know that buying and selling, lending, and deposits are called work? Scripture teaches "if he has not put his hand to his neighbor's goods" (Exodus 22:7, in the Hebrew). From where do we know that lawsuits, pleas, contestations, and all the acts of a court are called work? Scripture teaches "Benaiah and his sons were for the outside work over Israel, as officers and judges" (I Chronicles 26:29). From where do we know that betrothals and divorces are called work? Scripture teaches "But the people are many, and it is a time of heavy rain, and the work is not for one day or two" (Ezra 10:13). From where do we know that accounts are called work? As it says "And he went into the house to do his work" (Genesis 39:11).
