(Mishnah) - R. Yehudah: If a person writes over his property to his sons (before he marries, in order that the property will not be collected by the new wife if she collects her Kesubah money), he must write, "from today and after death".

R. Yosi: It is not necessary to write this.

If a person writes over his property to his son for after his death, he can no longer sell them because they are written over to his son; his son cannot sell it, because it is in the possession of his father.

If the father sold them, they are sold until he dies.

If the son sold them, the buyer cannot take them until the father dies.

The father may pick the produce of the field and feed it to whoever he wishes but any detached produce that remains goes to the inheritors.

(Gemara): R. Shimon ben Yakim asked R. Yochanan - why if a document stated, "From today and after death" is it valid for a gift; but "from today and after death" is not valid for a get?

Chevraya answered from R. Yochanan: The acquisition of a gift acts differently to the acquisition of a get.

R. Yosi bei R. Bun: He answered that a gift is different from a get and vice-versa. (This is the same answer as the Chevraya.)

R. Ila: For a gift, "from today" is clearly a valid gift. Why did he then write, "after death"? To allow him to continue eating the produce of the field. However, for a get, if he wrote, "from today", they are divorced. Why did he then write, "after death"? To withhold the divorce.

Question (R. Bun bar Kahana to R. Ila): Perhaps he only added that, in order to continue receiving that which she earns?

Answer (R. Ila): We do not find a woman who is married to one man and her earnings go to another.

R. Zeira praised R. Ila's answer and announced about him that he is a 'Builder of Torah'.
