This study examines marital elements in the Book of Tobit in light of the mores and beliefs of Ancient Israel and neighboring civilizations. After surveying key Old Testament and Ancient Near Eastern texts, this monograph outlines what the Book of Tobit reveals about ancient marital practices as well as the values it seeks to inculcate in its Diaspora audience with regard to marriage. Four aspects are analyzed: 1) the qualities a man should seek in a bride, 2) the marital customs observed by ancient Jews, 3) the role of God in marriage, and 4) the nature of the marital relationship.
