1. There is a dispute about the law of a Korah that is suspended in the air, and one that does not reach the walls of the Mavoy.
2. The Gemara presents two ways to understand the main point of the argument above (#1).
3. There is a dispute about whether one may carry in the area opposite the Lechi that is right outside the Mavoy.
4. Everyone agrees that a Lechi that is made by the side wall's protrusion into the entranceway is valid.
5. There is a dispute about whether a pole that is attached to the outer side of the wall of the Mavoy is a valid Lechi.


1. Tana Kama: If it is within three Tefachim of where it is supposed to be, it is valid. Raban Shimon ben Gamliel: It may be up to (but not including) four Tefachim away.
2. One opinion is that this proves that even if the Korah is less than three (Tana Kama) or four (Raban Shimon) Tefachim away from the wall on both sides, it is still valid.
3. Rebbi Yochanan: It is forbidden. Rava: It is permitted.
4. Since the people inside the Mavoy see the Lechi extending into their Mavoy, it is valid and permits carrying in the Mavoy, even though the people outside the Mavoy see nothing different (as they see merely a thicker outside wall).
5. In this case, the people inside the Mavoy do not see the pole, while the people outside do see it, since it is not flush with the width of the wall. Some say this is valid Lechi, and others disagree.
