Religious views on truth
There is no unilateral agreement among the different denominations of Judaism concerning truth. In Orthodox Judaism, truth is the revealed word of God, as found in the Hebrew Bible, and to a lesser extent, in the words of the sages of the Talmud. For Hasidic Jews truth is also found in the pronouncements of their rebbe, or spiritual leader, who is believed to possess divine inspiration. Kotzk, a Polish Hasidic sect, was known for their obsession with truth.
Jews
Without a Temple, Greek-speaking Jews no longer looked to Jerusalem in the way they had before. Judaism separated into a linguistically Greek and a Hebrew / Aramaic sphere. The theology and religious texts of each community were distinctively different. Hellenized Judaism never developed yeshivas to study the Oral Law. Rabbinic Judaism (centered in the Land of Israel and Babylon) almost entirely ignores the Hellenized Diaspora in its writings. Hellenized Judaism eventually disappeared as its practitioners assimilated into Greco-Roman culture, leaving a strong Rabbinic eastern Diaspora with large centers of learning in Babylon.
