Observation: Even so, when it wants to it can come down to this world.

Proof: This was the case regarding Rebbi Acha bar Yoshiya, as stated earlier in the Gemara. It is also like the incident involving Rebbi Banah in Bava Basra (58a) where he was marking burial caves. When he got to the cave of Avraham Avinu, Rebbi Banah found Eliezer the servant of Avraham at the mouth of the cave. Rebbi Banah asked, "What is Avraham doing etc.?" He said, "Let us go and see etc." (This is not our text in that Gemara.) This was despite the fact that Eliezer's soul was already stored underneath the Kisei ha'Kavod.

Implied Question: This is despite the fact that the Gemara says earlier (121a) regarding a minor who wants to put out a fire that if a minor is doing so because his father would like him to do so, it is forbidden. (Why does our Gemara permit telling a minor to violate Shabbos?)

Answer: The case here is where the minor is not doing both an Akirah and a Hanachah. Rather, it is as we say later regarding a donkey that when it is going he puts it on the donkey and when it rests he takes it from it. (One gives it to the minor in the same manner.)

Observation: Our Gemara implies that the law follows the Rabbanan. However, in Yevamos (113a) the Gemara implies that the law follows Rebbi Elazar, as Rav Chiya bar Ashi makes a statement in the name of Shmuel that is according to Rebbi Elazar's opinion.

Question: This is difficult. If so, why did the Gemara earlier say that if it is a choice between giving the wallet to an insane person or a child, we give it to the insane person? We say here that one may come to mix him up with an adult who is sane!

Explanation #1: Similarly, when they decreed the eighteen decrees, the decree regarding giving a wallet to a Nochri did not exist. They made this decree and thereby filled the measure of a Sa'ah completely, as if they put mustard in it.

Explanation #1 (cont.): Rebbi Yehoshua says that on that day they erased part of the measure of the Sa'ah itself. It is like putting nuts and pomegranates into a barrel of honey, causing the barrel to overflow. Similarly, before the decree regarding giving a wallet to a Nochri, they were allowed to carry it less than four cubits at a time. However, due to this leniency they would come to carry four cubits at a time. This is similar to a barrel that would spill over until the nuts and pomegranates were taken out. After they were taken out, the barrel would not overflow.

Explanation #1 (cont.): Similarly, when they made a decree to give a wallet to a Nochri, they also decreed that one cannot carry less than four cubits at a time. This understanding of Rebbi Yehoshua shows that both Rebbi Eliezer and Rebbi Yehoshua are praising the eighteen decrees.

Explanation #2: This is unlike Rashi's explanation that Rebbi Yehoshua is saying that the eighteen decrees were not a good thing, as the decrees were too strict.

Question: The Yerushalmi in the first chapter (of Shabbos) implies otherwise. The Yerushalmi there says that Rebbi Eliezer says that if it was (partially) empty and it was then filled, it is good. If a person pours sesame into a barrel that is full of nuts, it will hold as much sesame as is poured into it (as there is space between the nuts to hold a lot of sesame). Rebbi Yehoshua told him that if it was full and space was made, it is good. If a barrel is full of oil, as much water as is put into it will clear away the oil (and it will make space for the water).

Question: On the contrary! It appears to me that the Yerushalmi is a question on the Ri, as it is not possible to say the same explanation regarding water as the Ri explains regarding nuts and pomegranates (there is space between the nuts, while there is not space in the oil to allow water).

Question: This is difficult. When we permit carrying less than four cubits at a time, this should also be asked!
