Mary Joan Winn Leith has a very interesting discussion of this question in her article “Biblical Views: Who Did Cain Marry?” in the Biblical Archaeology Review 39.6 (2013): 22, 82–84. Her article was summarized by ChatGPT and the summary is below.
Summary of Mary Joan Winn Leith, “Biblical Views: Who Did Cain Marry?”
Mary Joan Winn Leith examines the long-standing question of Cain’s wife in Genesis and explains both traditional and modern scholarly responses.
She begins with the biblical problem itself. Genesis reports that Cain, after killing Abel, leaves Eden, settles in the land of Nod, and takes a wife (Genesis 4:16–17). Yet the text has only mentioned Adam, Eve, and their two sons. Cain also fears that “anyone who meets me may kill me” (Genesis 4:14), which implies the existence of other people. This has historically raised challenges to a literal or inerrant reading of the text.
Leith explains that the question is not modern. Early Jewish and Christian interpreters addressed it centuries ago. Their answers were based on the assumption that all humans descended from Adam and Eve.
- In Genesis Rabbah (5th century C.E.), Cain and Abel are said to have been born with sisters, and Cain married one of them.
- Early Christians similarly argued that Cain married one of the unnamed daughters mentioned later in Genesis 5:3–4, where Adam is said to have had “other sons and daughters.”
Leith then presents a modern critical explanation. She draws on sociological and anthropological insights about how ancient societies defined “us” versus “them.” Many ancient cultures considered only their own group fully human. She notes, for example, that Egyptians used the same word for “Egyptian” and “human,” while foreigners were depicted as subhuman. She also points to Israelite language such as calling Philistines “uncircumcised” to mark them as outsiders.
Using this framework, Leith suggests that the Genesis story assumes other people existed beyond Adam and Eve. However, from the Israelite storyteller’s perspective, only Adam’s line counted as fully human. Thus, Cain’s wife would have come from these “other” people, appropriate to his status as an exile whose sin had distanced him from his original human family.
Finally, she explains how changing historical circumstances affected Israelite theology. Early biblical traditions often assumed different nations had different gods, as reflected in Deuteronomy 32:8–9. After the Babylonian exile, Israelite thinkers developed a more universal view of God. The Priestly authors of Genesis 1, likely writing in exile, placed a universal creation account before the older Adam-and-Eve story. This broader theological framework made questions like “Who was Cain’s wife?” appear more pressing and logical to later readers.
In short, Leith contrasts:
- Traditional Jewish and Christian answers: Cain married his sister or another descendant of Adam and Eve.
- Modern critical scholarship: The story presumes the existence of other peoples outside Adam’s line, who were not regarded as fully “human” by the Israelite storyteller.
