Are Jews classified by blood or by living habits and beliefs?

According to the definition of halaka in Jewish law, all people who convert to Judaism (religious significance) and those born to Jewish mothers (national significance) belong to Jews. Jews originated from Hebrew in Israel or West Asia. There is a strong correlation between Jewish nationality, culture and religious belief, and Judaism is a traditional religion, which maintains the sense of identity of all Jews. Israel's unification law defines Jewish identity as the standard of matrilineal inheritance. All children of Jewish mothers will be recognized as Jews by Israel and have the right to immigrate to Israel.
