With regard to a vine branch that is tied to a pitcher, one may fill water with it on Shabbat because the branch became part of the vessel.

With regard to a window shutter, Rabbi Eliezer says: When it is tied to and hanging from the window, i.e., it is not touching the ground, one may shutter the window with it, because it is not considered building; and if not, i.e., it is touching the ground, one may not shutter the window with it. And the Rabbis say: Both in this case and in that case one may shutter with it.

GEMARA: We learned in a mishna there: In the case of a stone that is atop a barrel and one wants to open the barrel, he tilts the barrel on its side and the stone falls. Rabba said that Rabbi Ami said that Rabbi Yoḥanan said: They only taught this in a case where one forgets the stone atop the barrel; however, in a case where one places the stone atop the barrel intentionally, the barrel becomes a base for a prohibited object, and it is therefore prohibited to move the barrel. And Rav Yosef said that Rabbi Asi said that Rabbi Yoḥanan said: They only taught this in a case where one forgets it; however, in a case where one places it there, the stone becomes a cover for the barrel and it is permitted to use it like other barrel covers.

Rabba said: We raise an objection to our halakha from the mishna: With regard to a stone that is in a gourd used to draw water, if they fill it with water and the stone does not fall, one may fill with it on Shabbat. Apparently, if the stone is designated for a purpose, it is no longer set-aside. He rejects the proof: And that is not so, as these cases are not comparable. There, in the case of the stone in the gourd, since one attached it to the gourd, he rendered the stone a wall of the gourd and part of the vessel, unlike in the case of the stone atop the barrel.

Rav Yosef said: And we raise an objection to our halakha from the mishna: And if not, and the stone does fall, one may not fill with it. A stone that is not attached is not considered to be part of the vessel and is therefore set-aside. He rejects the proof. And that is not so, as these cases are not comparable. There, since he did not attach the stone to the gourd, he negates its status as a part of the vessel and it remains set-aside.

The Gemara explains: With regard to what do they disagree? One Sage, Rabba, holds that we require an action to change the status of a stone or another set-aside object into a vessel, and one Sage, Rav Yosef, holds that we do not require an action.

And they, Rabbi Ami and Rabbi Asi, follow their regular line of reasoning, as when Rav Dimi came from Eretz Yisrael to Babylonia he said that Rabbi Ḥanina said, and some say that it was Rabbi Zeira who said that Rabbi Ḥanina said: Once Rabbi Yehuda HaNasi went to one place and found a course of building stones, and he said to his students: Go out and think that you are designating these stones for Shabbat so that we may sit on them tomorrow on Shabbat, and Rabbi Yehuda HaNasi did not require them to perform an action with those stones. Thought alone was sufficient.

Rabbi Yoḥanan said: That is not what happened. Rabbi Yehuda HaNasi required them to perform an action to designate the stones. The Gemara asks: What action did he say to them to perform? Rabbi Ami said that Rabbi Yehuda HaNasi said to them: Go out and arrange the stones. Rabbi Asi said that he said to them: Go out and rub the mortar off of them. Rabbi Ami requires a more significant action to render the stones a vessel.

It was stated that there was a dispute with regard to this matter. Rabbi Yosei ben Shaul said: It was a new stack of beams, not stones. And Rabbi Yoḥanan ben Shaul said: It was the sounding pole of a ship used to determine the depth of the water. The one who said that Rabbi Yehuda HaNasi permitted sitting on a ship’s sounding pole, all the more so he permitted doing so in the case of beams. And with regard to the one who said that Rabbi Yehuda HaNasi permitted sitting on a stack of beams, but in the case of the sounding pole he would prohibit doing so because it is set-aside due to monetary loss, as he is particular about it that it will not become warped and damaged.

We learned in the mishna: With regard to a vine branch that is tied to a pitcher, one may fill water with it on Shabbat. The Gemara infers: If it is tied, yes, it is permitted; if it is not tied, no, it is prohibited. Let us say that the mishna is not in accordance with the opinion of Rabban Shimon ben Gamliel.

As it was taught in a baraita: With regard to hard branches of a palm tree that one cut for firewood or for construction, and then he reconsidered their designation and decided to use them for sitting, he must tie the branches together on Shabbat eve so that they will not be set-aside. Rabban Shimon ben Gamliel says: He need not tie them together, and nevertheless, it is permitted to move them. According to Rabban Shimon ben Gamliel, cut wood need not be specially prepared to be used on Shabbat.

Rav Sheshet says: Even if you say that the mishna is in accordance with the opinion of Rabban Shimon ben Gamliel, with what are we dealing here? With a case where the shoot is still connected to its origin, the vine. The Gemara asks: If so, he is making use of an item that is attached to the ground, and the Sages issued a decree prohibiting the use of any plant attached to the ground. The Gemara answers: This is referring to a branch attached to the vine below three handbreadths off the ground. A vine attached to the ground below three handbreadths off the ground was not prohibited in that decree, just as it is permitted to make use of tree roots adjacent to the ground. Rav Ashi said: Even if you say that it is referring to a branch that is detached, nevertheless, its use is prohibited due to the decree lest one cut and straighten the branch to prepare it for use with the bucket. Therefore, Rabban Shimon ben Gamliel teaches that there is no need for concern.

We learned in the mishna that Rabbi Eliezer and the Rabbis dispute the case of a window shutter and in what manner one is permitted to shutter a window on Shabbat. Rabba bar bar Ḥana said that Rabbi Yoḥanan said: Everyone agrees that one may not construct a temporary tent on a Festival for the first time, and needless to say, one may not do so on Shabbat. The tanna’im disagree only with regard to adding to an existing tent, as Rabbi Eliezer says: One may not add to an existing structure on a Festival, and needless to say, one may not do so on Shabbat. And the Rabbis say: One may add to a temporary structure on Shabbat, and needless to say, one may do so on a Festival.

We learned in the mishna that the Rabbis say: Both in this case and in that case one may shutter with it. The Gemara asks: What is the meaning of: Both in this case and in that case, in this context? Rabbi Abba said that Rav Kahana said:
