Answer : David's Star Symbol of Judaism Judaism is the religion of the Jewish community and one of the oldest and most monotheistic religions and the oldest religious traditions still practiced today. Judaism does not easily fit into Western segments such as religion , caste , ethnicity or culture. This is because the Jews consider Judaism to be a judgment of 4,000 years of history . During this long period Jews have experienced slavery , chaos , theocracy , conquest , occupation and exile and have been exposed to and influenced by ancient Egypt , Babylonia , Persia , Greek Hellenism , as well as the rise of nationalism influenced by the Enlightenment , socialism and modern movements. Thus , Judeo-American Professor Daniel Byrne argues that "being a Jew breaks down pure divisions of identity , because it is not national , not hereditary and religious , but in each of these dialectical tensions." Judaism is based on the Hebrew Bible , which contains the basic laws of Judaism. In particular , the Ten Commandments and the biblical history of Judaism form the moral and historical basis of other religions, including Christianity and Islam.
