Cain’s wife is an interesting figure in the Bible mainly due to the fact that it’s unclear what her name was and exactly who she was. All that’s really known about her is that she bore Cain a son after he was exiled to the Land of Nod. In other Christian writings, however, she is often referred to by the name of Awan (or Aven).
Cain’s Wife in the Land of Nod
In the Bible, the Land of Nod is not a physical place, although it is said to be “east of Eden”. The word “nod” is actually a Hebrew verb that means “to wander”. Essentially, being in the Land of Nod actually means that you are a nomad. People were often nomadic in those days so that wasn't necessarily considered a bad thing. However, that would eventually change as Cain and his descendants would establish a city there. Wherever it was, it was in the Land of Nod that Cain’s wife bore Cain’s son Enoch.
She Bore Enoch
Enoch is a very important person in the bible, which is why Cain’s wife is so important. However, Cain’s son Enoch is not the famous prophet Enoch. This Enoch was important because of the city that is named after him. Whether he built it himself or Cain by it in his name is unclear in the Bible. But for that alone, Cain's son Enoch is notable. Enoch and his descendants would end up growing this city. However, this City of Enoch would not be the same City of Enoch that would later see its inhabitants disappear after the prophet Enoch was taken into heaven by God. However, they are related, just not the same person.
Was Cain’s Wife Also His Sister?
It was common in the days of Genesis for people to marry their relatives. Cousins and even siblings often married in order to have children and grow the family. This was considered a completely normal practice in those days, as the world's population of humans was so small. So, whatever her name may have been, she was likely his sister.
