Recently there has been a lot of discussion about the origins of the people of Israel and who are the "real" descendants of the tribes of Israel. In this episode, we look at a responsum from the 1500s that indirectly addresses questions about how we "know" who is a Jew or Israelite. The question of how we know things is crucial for understanding the history of Halakhah, but also for understanding the world we inhabit and the beliefs if the people who are shaping it. This responsum from 500 years ago therefore has a great deal of contemporary importance, on many levels.

Here's a link to the responsum we studied, with my English translation: https://www.sefaria.org/Teshuvot_HaRadbaz_Volume_4.1290.1?lang=bi
