This chapter focuses on the presence of large settled populations of Jews and Samaritans, both urban and rural, in Palestine in the first to fourth centuries, and how Jewish identity and belief was expressed in the form of major literary works, in both Hebrew and Aramaic. It first considers two studies attributed to the Talmudic scholar, Saul Lieberman: one on the Greek context of Jewish life in Judaea/Palaestina in the first to fourth centuries; and one on the extensive presence of transliterated Greek words, and of Greek concepts, in rabbinic literature. It then looks at the co-existence and conflict between religious and ethnic communities in Palestine, citing evidence provided each by Sozomenus and Epiphanius. More specifically, it discusses some reports of overt inter-communal conflicts, which often involve Samaritans rather than Jews. It also describes Samaritan religion and culture, Jews and Judaism in Palestine, and the Jewish diaspora in the Roman Near East.
