Juaism (from the Greek Ioudaïsmos, derived from the Hebrew יהודה, Yehudah, "Judah"; in Hebrew: יַהֲדוּת, Yahedut, the distinctive characteristics of the Judean eáqnov) is the religion of the Jews, based on principles and ethics embodied in the Hebrew Bible (Tanakh), as further explored and explained in the Talmud. In 2007, the world Jewish population was estimated at 13.2 million people—41% of whom live in Israel and 59% in the diaspora.
