  • Radbaz vol. 1, no. 40 - Ransoming Captives

    Radbaz vol. 1, no. 40 - Ransoming Captives
    Dec 20 2023
    Radbaz, R. David Ibn Abu Zimra, addresses the question of what constitutes 'overpaying' to ransom a Jewish captive. This episode gets into the economic and political realities of the 16th century in the Mediterranean basin, including the burgeoning slave trade, and the resulting attention to the great mitzvah of pidyon shevuyim, ransoming captives. Here's a link to the responsum: https://www.sefaria.org/Teshuvot_HaRadbaz_Volume_1.40.1?lang=bi And here's a link to the first part of my series on Rav Ovadiah Yosef's teshuvah on the Entebbe hostages: https://jewishreviewofbooks.com/contemporary-israel/14972/rabbi-ovadia-yosefs-and-the-halakhot-of-hostages-part-i/

    Krakenfruit (the Buddha's Hand Etrog)
    Sep 28 2023

    Two of the greatest rabbis of the Bavli Jewish community in recent centuries address the status of a new type of fruit that arrived from the Far East. Is it a kosher etrog?

    The question is addressed in two responsa, one by R. Abdullah Somekh and one by his student, R. Yosef Hayyim, both of Baghdad.

  • Public and Private Penance (Responsa Maharam Lublin)

    Public and Private Penance (Responsa Maharam Lublin)
    Sep 24 2023

    We generally think of confession and penance as either a private matter between a person and God, or as a matter between the perpetrator and victim of a wrong. But not that long ago there were forms of penance that were very public. What's the idea behind them, and what can they teach us about social healing today?

    We will be studying and discussing a series of responsa by Maharam Lublin. Here is a link to the responsa: https://www.hebrewbooks.org/pdfpager.aspx?req=1937&pgnum=39

  • Book Journeys, Some Updates, and the Hoshanot Mosh Pit

    Book Journeys, Some Updates, and the Hoshanot Mosh Pit
    Jun 28 2023
    The episode begins with some updates. First, an introduction to the "Book Journey" that I will begin next week. Sign up link: https://18forty.org/bookjourney/ This is an outgrowth of the 18forty podcast episode in which R. David Bashevkin and I discussed the vision and reality of a Jewish polity governed by Halakhah. Here's a link to the episode: https://18forty.org/podcast/elli-fischer-can-israel-follow-jewish-law/ I was also a recent guest on two other podcasts. First, Rav David Silverstein and I discussed the nature of rabbinic authority on Yeshivat Orayta's "Tzarich Iyun" podcast: https://open.spotify.com/episode/71aX8L9IA2j1QY78dOoGff?si=577b0ae9ed414716 Finally, a few months ago I was hosted by Darcy Walters for an episode of her "Desert Island Torah" podcast. Here's a link: https://podcasters.spotify.com/pod/pod/show/desert-island-torah/episodes/Ep-81-with-Rav-Elli-Fischer-e23me3f The responsum that we study in this episode was penned by R. Yisrael Isserlein, better known as the Terumat HaDeshen. We spend some time discussing when and where he lived, who his influences were, why his rulings are so influential, and what makes his Sefer Terumat HaDeshen so unique. Then we go on to the teshuvah itself, which addresses an issue that is not-quite-halakhah. The setting is almost surreal: Person A allegedly used the crush of hoshanot in shul as cover to maim Person B while maintaining plausible deniability. This is an important matter of social and communal governance, but halakhic standards of evidence seem to set too high a bar to take any action. How did R. Isserlein resolve the matter? Here's a link to the teshuvah in Sefariah, with my translation: https://www.sefaria.org.il/Terumat_HaDeshen%2C_Part_II.210?lang=bi
