The Bible, a cornerstone of faith and a profound literary work, offers a multifaceted view of human relationships and societal structures throughout its narrative arc. Among the most debated and often misunderstood aspects of its historical accounts is the prevalence of polygamy, particularly within the Old Testament period. This book is born out of a desire to engage with this complex subject through the lens of theological research and sound biblical scholarship. We aim to move beyond superficial readings and into a deeper understanding of how Scripture addresses, presents, and ultimately contextualizes the practice of plural marriage. Our intended audience comprises those who are drawn to the intricacies of biblical studies, theology, and the historical interpretation of scripture, particularly within a Christian framework. This includes pastors who shepherd congregations, seminary students who are honing their theological acumen, seasoned theologians engaged in scholarly discourse, and lay Christians who possess a sincere yearning for a more rigorous and nuanced comprehension of biblical passages concerning marriage and family. The readers we envision are not passive recipients of information but active participants in the intellectual and spiritual journey, appreciating detailed exegesis, robust historical context, and compelling theological argumentation. We commit to a writing style that balances academic precision with accessible exposition, ensuring that complex concepts are thoroughly explained without succumbing to excessive jargon. The narrative approach, weaving historical accounts with scriptural analysis, will be employed to make the material engaging and relatable. Throughout this exploration, we will address specific scriptural instances, such as the marital practices of Abraham, David, and Solomon, contrasting them with the emphasis on monogamy found in later New Testament teachings. The theological concept of Christ and the Church as a unified bridegroom and bride will also be a central focus, highlighting its profound symbolic significance for the New Covenant. This study is not an attempt to vindicate polygamy, but rather to understand its place within the historical unfolding of God's redemptive plan and to illuminate the normative ideal of marriage as progressively revealed in Scripture, culminating in the New Testament's clear affirmation of monogamy.
