Jews (Hebrew:? Yehudim), also known as the Jewish nation, is an ethnic group widely distributed in all countries of the world. According to the definition of Halaka, the Jewish law, all people who convert to Judaism (religious meaning) and those born to Jewish mothers (national meaning) belong to Jews. Jews originated in Israel or Hebrew in West Asia. There is a strong correlation between Jewish nationality, culture and religious beliefs, and Judaism is a traditional religion that maintains the sense of identity among all Jews. Judaism does not welcome foreigners to convert to Judaism, and foreigners who want to convert to Judaism must pass the test. However, in history, a small number of people with different skin colors have become part of the Jewish community by converting to Jewish religion, and Jews have thus developed from a nomadic people in the Arabian Peninsula to one of the world-wide ethnic groups all over the world.
