Siman - Shabbos Daf 44

  • מוקצה מחמת מיאוס – Muktzeh due to becoming repugnant

The next Mishnah introduces a machlokes regarding the muktzeh status of a lamp:

Tanna Kamma: One may move a new lamp but not an old lamp because he holds of מוקצה מחמת מיאוס - an item becomes muktzeh due to it becoming repugnant, and a used clay lamp becomes repugnant after use.

Rebbe Shimon: One may move all lamps except for a lamp that is actually burning on Shabbos. He does not hold of מוקצה מחמת מיאוס. The Gemara later on will clarify that he prohibits moving a lit lamp because the wick and oil have become a base to the flame which is muktzeh.

  • Verbally designating a bed for use to store money

Rav Yehudah said in the name of Rav that if someone verbally designated a bed for the storage of

money and then placed money on it, even during the week, it is subsequently forbidden to move on Shabbos, even if the money was removed before Shabbos. If he never had used it for money, then it would be permitted to use on Shabbos. The designation alone would not make the bed muktzeh.

  • Halachos related to the removable wheel of a wooden coach

A Mishnah was brought from Keilim that teaches that in a case where a wooden coach has a removable wheel, the coach and wheel are considered two separate items. Therefore:

If the coach becomes tamei, the wheel does not automatically become tamei with it.

The wheel is not measured with the coach to determine if it is has the liquid volume of forty se’ah or greater. An object forty se’ah or greater is considered too large to be portable and therefore does not contract tumah.

In a case where the coach is large and serves as a barrier between a corpse and its contents, the wheel itself does not serve as a barrier and it becomes tamei.

If money was on the wheel on Shabbos, the coach can not be dragged since the wheel becomes a bosis l’davar ha’asur, a base for a forbidden object.
