How long did Cain live?

Answer 1

Interestingly enough, neither The Bible nor the Torah have anything to say about the life of Cain apart from his descendants. In most cases, the account will give the children the individual had and follow it with "and his years were" followed by how long they lived. The Midrash, however, suggests that Cain lived to see the seventh generation of his own offspring- Roughly 500 years.

Answer:

Piecing together two midrashim yields Cain's lifespan as 130 years.

Answer 2

According to the Bible, Cain lived for 930 years.
