Concubines, Wives, and Social Accommodation in the Old Testament

The Old Testament records both wives and concubines, yet it does not describe an organized church-state apparatus defining these categories. The distinction between wife and concubine appears as a social and legal differentiation within the culture, not as a divinely instituted ideal.

First Appearance and Pagan Background

The first explicit mention of a concubine occurs in Genesis 22:24, where Nahor, Abraham’s brother, is said to have a concubine, Reumah, who bore him children. This context is important: Abraham’s extended family appears within a pagan, idolatrous environment. There is good reason to believe that Abraham’s father was involved in idolatry. The practice of taking concubines arises in that pagan milieu, not as part of an original, creational pattern.

Thus, from the outset, concubinage in Scripture is linked to existing social practice, not to a revealed ideal. The text simply reports that this is what was happening among people, including those from whom Abraham came.

Accommodation versus Ideal

Throughout the Old Testament, God’s law sometimes accommodates social realities that fall short of his creational intention. An example is the certificate of divorce. Jesus later comments that Moses permitted divorce “because of the hardness of your hearts,” but adds that “from the beginning it was not so.” The permission of divorce in the Mosaic law is an accommodation to human sin and social chaos, not a reflection of the original design for marriage.

Concubinage functions similarly. The Scripture recognizes and regulates the practice without endorsing it as God’s plan. The narratives show that concubines are present, and the law makes provision for their children and their treatment, yet the original pattern remains one man and one woman in a faithful one-flesh union.

How a Concubine Differed from a Wife

In practice, a concubine was a woman who had a sexual relationship with a man and bore his children, but without the full legal and social status of a wife. Several distinctions emerge in the Old Testament environment:

• Status: A wife occupied the primary and honored position in the man’s household. A concubine was secondary, attached to the man but of lower rank, often reflected in her background (slave, captive, or socially lower standing).
• Rights of Children: Children of a wife usually held priority in inheritance and family leadership. Children of concubines, while recognized as the man’s offspring, often had reduced or contested claims.
• Legal and Social Protection: Wives, as such, enjoyed stronger protections regarding provision, inheritance, and public acknowledgment. Concubines were more vulnerable, their security dependent on the man’s favor and the social norms of the household.

These distinctions do not arise from an explicit divine directive that men should have concubines. Instead, they reflect the kinds of social and legal categories that emerge when societies institutionalize practices that deviate from the one-man, one-woman ideal.

Biblical Evaluation of Concubinage

The Old Testament does not present concubinage as a model to emulate. Where concubines appear, they are often part of complex and troubled family arrangements. For example, Hagar’s situation with Abraham and Sarah introduces significant tension and conflict. Other narratives involving concubines likewise reveal disorder and moral ambiguity.

The law’s regulation of concubines does not mean endorsement, any more than the regulation of divorce means that divorce reflects the original intention for marriage. The law deals with people as they are in a fallen world and seeks to limit harm and injustice within the realities already present.

Concubines, Wives, and One-Flesh Union

From the perspective of the one-flesh principle, a concubine is still involved in a real sexual union with the man. That union carries moral weight. Yet the society distinguished between that union and the primary covenant bond with a wife. This societal accommodation produced a layered household structure: one or more wives with full standing, and additional women with whom the man had sexual relations but who lacked full status and rights.

In other words, the difference between wife and concubine in the Old Testament is largely a matter of social and legal category, not of the physical nature of the relationship. Scripture records that such arrangements existed; it does not present them as the creational norm.

Conclusion

In Old Testament culture, without an organized church-state system defining marriage, a concubine was understood as a secondary partner: a woman who belonged to a man sexually and bore his children, but without the full standing, protections, and inheritance rights associated with a wife. The category arises from social accommodation to fallen practices, not from God’s original pattern for marriage. The law and narratives recognize and regulate concubinage, but the creational ideal remains a faithful, exclusive, one-flesh union between one man and one woman.
