Marriage in Judaism is the documentation of a contract between a Jewish man and a Jewish woman in which God is involved. In Judaism, a marriage can end either because of a divorce document given by the man to his wife, or by the death of either party. Certain details, primarily as protections for the wife, were added in Talmudic times.
Non-Orthodox developments have brought changes in who may marry whom. Intermarriage is often discouraged, though opinions vary.
In traditional Judaism, marriage is viewed as a contractual bond commanded by God in which a man and a woman come together to create a relationship in which God is directly involved. Though procreation is not the sole purpose, a Jewish marriage is traditionally expected to fulfil the commandment to have children. In this view, marriage is understood to mean that the husband and wife are merging into a single soul, which is why a man is considered "incomplete" if he is not married,
