Daf 9a
across [or, over] himself, he is liable. — There it does not come to rest [in the place of non-liability], whereas here it does. 'Others state, A threshold serves as two domains: if the door is open, it is as within; if the door is shut, it is as without.' Even if it has no stake? But R. Hama b. Goria said in Rab's name: That which lies within the opening requires another stake to permit it. And should you answer that [the reference is to a threshold which] is not four square: surely R. Hama b. Goria said in Rab's name: That which lies within the opening, even if less than four square, requires another stake to permit it!-Said Rab Judah in Rab's name: The reference here is to the threshold of an alley, half of which [threshold] is covered and half uncovered, the covering being toward the inner side: [hence] if the door is open, it is as within; if the door is shut, it is as without. R. Ashi said: After all, it refers to the threshold of a house, and e.g., where it is covered over with two beams, neither being four [handbreadths wide], and there are less than three [handbreadths] between them, while the door is in the middle: if the entrance is open, it is as within, if shut, it is as without. 'But if the threshold is ten [handbreadths] high and four broad, it is a separate domain.' This supports R. Isaac b. Abdimi. For R. Isaac b. Abdimi said, R. Meir used to teach: Wherever you find two domains which are really one, e.g., a pillar in private ground ten high and four broad, one may not re-arrange a burden thereon, for fear of a mound in a public domain.
