Who has the bloodline of Cain?

The bloodline of Cain, according to The Bible, refers to the descendants of Cain, the firstborn son of Adam and Eve, who is known for committing the first murder by killing his brother Abel. The genealogical account in Genesis 4 details Cain's lineage, including notable figures like Enoch, who built a city named after his son Irad. This lineage is often contrasted with the bloodline of Seth, another son of Adam and Eve, which is associated with righteousness. The bloodline of Cain is sometimes symbolically linked to themes of sin and moral failure in theological discussions.
