The sefer Seder Hadorot brings different opinions as to how old Hevel was when he was killed by Kayin.

Bershit Rabbah Ch. 22: 50 days (or 90 days [Seder Hadorot says 50 is a printing mistake])

Ibn Ezra: 1 year

Tanchuma, Abarbanel and Josephus: 100 years.

According to the former opinions... does this mean that Kayin and Hevel developed really quickly or were they somehow born fully developed?


One of my Rebbes said in the name of the Zohar that they were born developed like a 20 year old.

  • Anyone know where the source of this is? Thanks. Best I've found so far is Bereishis Rabbah 14:7 saying that Adam and Chava were created as 20 year olds.
