Today’s Talmud pages, Nazir 55 and 56, teach us that the rabbis considered all other lands except for Israel impure, for a vast array of physical and spiritual reasons. Director Matthew Mishory joins us to talk about his new film, Who Are the Marcuses?, which tells the incredible story of the two unknown Jewish philanthropists behind the single largest gift ever in Israel's history, and how it changed the way Israel, and the world, think about water. What breakthrough did the Marcuses make possible? listen and find out. Take One is a Tablet Studios production.
