of Jerusalem by the Jordanians in 1947–1949 Palestine war until the capture by the IDF in the Six-Day War (1967), he vowed not to leave his home. Finally, since Israel's independence (1948), he vowed not to leave the Holy City of Jerusalem and, in fact, left Jerusalem only on 3 occasions after that (24 years until his passing), with each such departure being formally approved by a special Beith Din (a Rabbinical Court) granting him temporary permission to depart from his undertaking.
