|Where did Cain’s wife come from?
|According to Genesis 3:20 Eve is the mother of all living people and Cain was her first son. (Gen.4:1) Genesis 5:4 tells us that Adam and Eve lived for 800 years after the birth of Seth, when they were 130 years old, and they bore other children. Cain’s wife would have been from these descendants. She was possibly a sister or a niece. Keep in mind that “in the beginning” close relatives were a person’s only choice. With the recently created gene pool, they didn’t have the mutational defects built up in their DNA which cause such severe results in offspring of close relatives today. It wasn’t until the days of Moses, Lev. 18-20, that marriages between close relatives were forbidden.
