Hanazir Ayerushalmi is a film about Rabbi David Yehuda Arieh Leib Cohen (1887-1972), otherwise known as Hanazir Hayerushalmi (The Jerusalem Nazirite). Rabbi Cohen dedicated his life to the ways of the Nazirite, he did not cut his hair, drink wine, or eat meat. Besides his extensive knowledge in Jewish writings, he also held a PhD in Western philosophy, and his writings would refer to both of these traditions. His most important writing, Kol Hanevua, explains the importance of hearing and listening in Judaism rather than reading and writing which is more important in western philosophy. The film additionally explains that Rabbi Cohen transcribed the Kabala through melodies that he wrote, one of which is performed on the cello in this film.
