Topic

Whether difficult use counts as use (the pit and the shallow pool), רב יהודה on flipping a bundle of reeds, and the threshold as a מקום פטור

Overview

The amud opens with a ברייתא about a person who sets his שבת place in רשות הרבים and puts his עירוב in a pit. 'Above ten טפחים' the עירוב works, and 'below ten' it fails. The גמרא shows this must mean a shallow pit. That seems to prove that תשמיש על ידי הדחק שמיה תשמיש, against רבא. רבא gives two answers. In the first, both the person and the pit are a כרמלית. In the second, the food is in a כרמלית and the ברייתא follows רבי, who holds that a שבות was not decreed during בין השמשות. רבא then proves his rule from the doubled wording in the משנה of a shallow pool (רקק מים): walking with difficulty counts as walking, but use with difficulty does not count as use. Next, רב יהודה rules that flipping a bundle of reeds along the ground creates no liability until it is lifted. The גמרא then returns to the ברייתא of a person standing on a threshold. After rejecting רשות הרבים, רשות היחיד and כרמלית, it concludes the threshold is a מקום פטור smaller than four by four טפחים, supported by רבי יוחנן. Finally, the ruling that passing an object across through the threshold leaves all three פטור is raised as a challenge to רבא, and that challenge continues on the next amud.
