Shabbat

Now if a lamp, though made for that purpose, may be handled if it was not lit, how much more so a bed, which was not made for that purpose! Rather if stated, it was thus stated: Rab Judah said in Rab's name: In the case of a bed which was designated for money, if money was placed upon it,  it may not be handled; if money was not placed upon it, it may be handled. But if it was not designated for money, then if money is lying upon it [now], it may not be handled; if money is not lying upon it, it may be handled, provided that there was none upon it at twilight. R. Eleazar objected: As for its wheel-work, if detachable, it has no connection therewith, is not measured with it, does not protect together with it in [the matter of] a covering above the dead, and it may not be rolled on the Sabbath if there is money upon it.  Hence if there is no money upon it [now] it is permitted, though it was there at twilight? — That is according to R. Simeon, who rejects [the law of] mukzeh,  whereas Rab agrees with R. Judah.
