(R. Yudan): (Answering the Gemara's question as to the contradiction between Rabban Shimon ben Gamliel and the Baraisa...) Rabban Shimon was discussing when a Cheresh himself separates Terumah or writes a Get; the Baraisa was discussing when he orders a Sofer to write a Get.

Question (R. Binyamin bar Levi): If he had the understanding to write the Get (for the sake of the husband and wife), he also has the understanding to order it to be given; if not, not.

Answer #2 (R. Avdimi): A Cheresh cannot appoint an agent.

Answer #3 (R. Yosi bei R. Bun): The Baraisa is discussing a heathy person who became a Cheresh - we are concerned that he became insane before he became a Cheresh. So why isn't it a valid Get in the Mishnah? As perhaps when he said 'Get', he was referring to another document (which are also referred to as Gitin, but he did not want a Get written to his wife). (Rabban Shimon ben Gamliel was discussing when he became a Cheresh through illness and there was no concern that he first became deranged). So the Baraisa should be read as follows...

When must he nod three times? When he became a Cheresh after being healthy (and there is concern that he might have first become deranged), but if he lost his speech through regular illness, it is enough that he nod only once.

Who is the Tanna who holds that the Terumah of a Cheresh is not Terumah? It's not R. Yehuda, as the Baraisa taught -

(R. Yehuda): The sons of R. Yochanan ben Gudgodah were all Cheresh, and all of the Taharos of Yerushalayim were supervised by them. (This shows that a Cheresh is able to be careful with Taharah.)

Rebuttal (Rabbanan to R. Yehuda): They were relied upon because Taharos only require guarding but not 'Machshava' ('thought') and can therefore be watched by a deranged person, a Cheresh or a child, but since Terumah and Ma'asros need Machshava.

Question: Are they are not disqualified due to their lack of awareness?

Answer (R. Yosi citing R. Ila): The pasuk did not write 'Machshava'; it merely wrote about 'watching'.

The signs of a deranged person are one who goes out (alone) at night; one who sleeps in a graveyard, one who tears his garment and one who loses that which he is given.

(R. Huna): He must have all of these behaviours, otherwise I could say that he goes out at night to cool off; he sleeps in the graveyard in order to have a spirit of witchcraft rest on him; he tears his garment because his mind is completely preoccupied with other things; he loses that which he's given because he has an illness (of the mind) called Kudaikus.

(R. Yochanan): Even if he has one of them, he is considered a deranged person.

(R. Bun): R. Yochanan's ruling is logical in the case of losing that which he's given - even the craziest person doesn't lose everything he's given. Kundaikus and Kurdaikus don't have any of these behaviours.

Question: What is Kurdaikus?

Answer (R. Yosi): He is bewildered and cannot calm down.

A case once came before R. Yosi of a weaver who was given a red thread amongst his black threads and he didn't notice it at all. They put a black thread amongst his red threads and he also didn't notice at all. R. Yosi commented, "This is the example of Kurdaikus about which Chazal spoke''.

If he is sometimes insane and sometimes sane, he is considered healthy in all matters. When he is insane, he is insane for all matters; when he is sane, he is sane for all matters.

A case came before Shmuel, who ruled that when the man is healthy (Chalim), have him give his wife a Get.

Question: Is Shmuel is like Reish Lakish who disagreed (in Maseches Gitin Yerushalmi) over the case of a person who instructed a Get to be written to his wife and then became sick with Kurdaikus - R. Yochanan allows him to give the Get immediately and Reish Lakish only allowed it after he has recovered...?

Answer: No, Shmuel is teaching something even more than Reish Lakish, as Reish Lakish only allows it when he is completely healed, but Shmuel allows it even if he is not yet completely healed.

What is the source that the word 'Chalim' means healthy? As the pasuk states (Yishaya 38:16), "...and You healed me ('Vatachalimaini') and gave me life ('Vehachayaini')''.
