In our Gemara, Rabbi Yosei bar Ḥanina teaches that a Rabbinic enactment was made in Usha establishing that if a woman sold her nikhsei melug (usufruct property – possessions that remain the property of the wife during marriage), in the event that she passes away before her husband, he can collect the land from the purchaser, since he has a primary claim to it.
What are takkanot Usha?
According to the Gemara in Massekhet Rosh HaShana (31a), at the time of the destruction of the Temple, as the Jewish people were sent into exile, God joined them by removing His presence from the Temple in a series of stages. In a parallel move, the Sanhedrin gradually removed itself from its offices on the Temple Mount, as well, making its way to the Galilee, where most of the remaining Jews were to live under Roman rule.
The Sanhedrin’s first stop after leaving Jerusalem was the city of Yavne, which was established as a center of Torah study by Rabban Yoḥanan ben Zakkai, and became most famous under the direction of Rabban Gamliel of Yavne. Throughout its continuing travels, the Sanhedrin was headed by descendants of the family of Hillel.
It appears that the Sanhedrin was moved to Usha in the aftermath of the Bar Kokheva revolt, where a series of Rabbinic ordinances – called takkanot Usha – were established. Under the leadership of Rabbi Shimon ben Gamliel there was an unsuccessful attempt to return the Sanhedrin to Yavne, but due to the overwhelming devastation in the southern part of the country, they returned to the Galilee, first to Usha and then to Shefaram.
Takkanot Usha deal mainly with establishing the norms of monetary relationships within families. While these enactments were not included in the Mishna, they were known to the amora’im based on oral traditions.
