Do Jews share wives?

Did Jewish Men Ever Have Multiple Wives?

It’s a question that often arises when reading the Hebrew Bible: Did Jewish men historically share wives—or more accurately, practice polygamy? The answer, rooted in both scripture and evolving tradition, is more nuanced than it first appears.

Yes, the Pentateuch—the first five books of the Hebrew Bible—includes accounts of prominent figures with more than one wife. Abraham had Sarah and Hagar. Jacob famously married both Leah and Rachel. King Solomon, according to the Bible, had hundreds of wives and concubines. Throughout the Prophets and Writings, polygamy appears as part of the social fabric of ancient times, not presented as ideal but as a reality of the era.

Yet, Jewish practice evolved significantly over time. By the 11th century CE, a major shift occurred. Rabbeinu Gershom, a leading Jewish scholar in medieval Europe, issued a decree—known as a herem—that effectively banned polygamy among Ashkenazi Jews. This ban, which also included protections for women in marriage, became widely accepted across most Jewish communities.

While some Sephardic and Mizrahi communities held differing views for a time, the normative practice in Judaism today—whether Orthodox, Conservative, or Reform—is strictly monogamous. The historical existence of polygamy in biblical times does not reflect modern Jewish life, where marriage is understood as a covenant between one man and one woman.

So, while the Bible records polygamy among the ancestors, Jewish law and tradition have long since moved away from it. The evolution reflects a deeper journey—from ancient customs to ethical refinements shaped by centuries of interpretation and communal values.
