Siman - Shabbos Daf 92

  • Carrying above ten tefachim in reshus harabim

The next Mishnah in the perek states that one is only liable for carrying if one carried in a normal manner. Included in the list of normal forms of carrying, is carrying on one’s shoulders, for that is how bnei Kehas carried the keilim of the Mishkan.

Rebbe Elazar learns from the carrying of bnei Kehas, who carried the keilim at a height of more than ten tefachim from the ground, that if one transfers a load from one reshus to another by hand, and keeps it in the air more than tefachim above the ground, that he is liable.

Rashi explains that even though ten tefachim above a reshus harabim is considered a makom petur, and if one were to throw an object in a reshus harabim and it landed (i.e. got stuck) on a side of the wall ten tefachim above the ground he would be exempt, in this case he is liable because this is the way bnei Kehas transported the keilim.

  • The difference between carrying in front or behind

The following Mishnah states that if one intended to take an object out in front of him but in mid-transfer it slipped behind him, he is exempt. However, if he intended to take the object out behind him and it slipped in front of him, he is liable.

Rava explains that in the first case when the person carried the object out in front of him, his intent was to guard it well. Since it slipped behind him, it was guarded poorly. Since his initial machshava (thought) was not fulfilled, Rashi says that it is a case of מתעסק .

In the second case where the person carried the object behind him, he only intended a minimal guarding. When it slipped in front, it resulted in even a better guarding, making him liable since he was pleased with the result.

Two people carrying an object

The following Mishnah introduces a machlokes Tannaim in a case where two people carry out an object that neither individual could carry alone :

The Tanna Kamma holds that they are both liable.

Rebbe Shimon says they are both exempt.

The Gemara brings a Baraisa that states that if one person was capable of carrying the object alone, and the other one was not capable, then everyone will agree that “he” is liable. The Gemara on 93a will clarify which one is liable.
