The primary role of the wife was to be the mother of sons, and when she had fulfilled this requirement her status rose accordingly. The wife was not expected to take any part in financial administration, even her own funds being administered by her husband. If she became a widow, however, she might manage funds and property until her sons came of age. It was the responsibility of the husband to provide for his wife and family. An Exclusive Relationship.
Marriage is an exclusive relationship.
One cannot relate wholeheartedly in this way to more than one person at a time. Only under certain special conditions may the principle of indissolubility be set aside. Promiscuity is likewise ruled out. Such unions are neither exclusive nor enduring. Moreover, they violate the holiness that inheres in biblical marriage.
