Tuhia he tohutoro mo tenei pene - I whanau a Ephraim Elimelech Urbach i Białystok, Poland, ki tetahi whanau Hasidic. I ako ia i Roma me Breslau, i reira i whakawhiwhia ai ia ki te whakahaerenga. I heke ia ki te Mana Whakahaere o Palestine i te tau 1937. I mahi ia hei kaitiaki i roto i te ope o Ingarangi i te Pakanga Tuarua o te Ao. I uru hoki ia ki te Pakanga Independence o Iharaira i te tau 1948
