Even in the days of Cain and Abel there were doubtless very many people whose names are not recorded. In the testimony of Moses we have this statement: "And the days of Adam after he had begotten Seth were eight hundred years: and he begat sons and daughters" ( Genesis 5:4 ). Other evidences are
- Cain's fear of death at the hands of his fellowmen,
- God's recognition of the ground of this fear and the means used to protect him,
- Cain had a wife ( Genesis 4:14-17 ).
