Who Was Cain's Wife?
1) Direct Answer
Cain married his sister—one of the daughters of Adam and Eve.
2) Scriptural Explanation
- The Bible says Adam “begat sons and daughters” (Genesis 5:4). Those daughters are not named, but they were there.
- Eve is called “the mother of all living” (Genesis 3:20). So every human—including Cain’s wife—came from Adam and Eve.
- Later God forbade close-kin marriages (Leviticus 18), but that law came after the early generations.
3) Simple Clarifying Logic
- In the beginning there was only one man and one woman. If Cain had a wife, she had to come from that same family.
- If his wife came from another people, then Eve would not be the mother of all living. That would contradict the Scripture.
4) Reinforcing Statement
Now notice, Cain didn’t find a different race; he took a sister. That’s how the human family multiplied at the start. The Bible keeps it simple.
