Yhoshua Leib moved to the Old City of Jerusalem, where he became involved first with Agudat Yisrael, then the Edah HaChareidis and a controversial splinter sect led by Amram Blau known as Neturei Karta. When the 1947–1949 Palestine war started, the Jordanian Legion captured the Old City, Yhoshua Leib fled first to Katamon and then to Meah Shearim.[1] He worked for several years as a tutor and yeshivah rebbe, and even as a bricklayer and furniture carpenter.[1]
