Many Christians have been taught that Cain went to Nod, found a wife, got married, and had a son. But if Adam and Eve were the only two people that God created, where did the people of Nod come from?
First, let’s read the actual words of Genesis 4:16–17 Then Cain
The Bible does not say that Cain went to Nod and later found a wife there. Rather, the implication in Scripture is that he already had a wife when he went to Nod. The event that took place in Nod was that he “knew” his wife—had sexual relations with her—and she conceived and gave birth to a son.
Genesis 5:4 makes it clear that they had multiple sons and daughters: The days of Adam after he fathered Seth were 800 years; and he had other sons and daughters.
So, since we are “one blood” descended from Adam and Eve, the only person Cain could have married would have been a sister or a niece.
The immediate reaction to Cain marrying his sister or niece is often shock or disgust. Today, marrying close relations is called incest. However, approximately 6,000 years ago, God did not forbid marriage between close relatives.
Q: Why?
A: Adam and Eve were created perfect. It wasn’t until after the fall that suffering and death affected mankind and every other living thing. One aspect of this suffering would have been mutations in the DNA that result in disease. Since Adam and Eve were created genetically perfect, their children would have had few mutations. Mutations in subsequent generations would have continued to increase and accumulate. Eventually, it became too dangerous to marry a close relation because of the increased likelihood of inherited disease.
During the time of Moses, approximately 2,500 years after creation, God forbade marriage between close relatives (Leviticus 18:6–18). It seems that one reason was health."
