BAVA BASRA 159 - A week of learning has been dedicated towards meriting a Refu'ah Sheleimah for Eliezer Lipa ben Yetta, by Mr. and Mrs. Kornfeld of Yerushalayim.


1. The Gemara discusses the case of a man who sells the rights to his father's property before his father dies, but then he dies before his father.
2. A grandson inherits his grandfather directly.
3. If a man signed as a witness on a document, and he then became a thief, he may not testify regarding his signature.
4. Similarly, if a man signed as a witness and he then became a son-in-law of one of the parties, he may not testify regarding his signature.
5. The law that relatives may not testify for each other is not because we suspect they will lie for each other.


1. The Gemara says that the man's son inherits the properties that the man sold (since the man never really owned them, because he died before his father), as a grandson inherits from his grandfather (when the grandfather's own son predeceased him).
2. In other words, Chanoch, the son of Reuven, does not inherit Yakov because Reuven inherits him first, and then Chanoch inherits Reuven. Rather, the Torah teaches, "In place of your fathers will be your sons," implying that your father will be inherited by your son (i.e. Chanoch will inherit Yakov).
3. However, other people may testify that they previously validated his signature. His testimony will then be valid in that document, as he signed it before he became disqualified from testifying.
4. However, others may testify that they previously validated his signature or that this is his signature (unlike the previous case where they may not do the second of these two options).
5. If this were the reason, we would allow people who are known to be credible, such as Moshe Rabeinu and his brother Aharon, to testify for each other or for their father-in-law! Rather, it is forbidden simply because the Torah said so.
