Will read in a full screen later, but from discussion with several Hebrew rabbis and acquaintances, it is safe to say none were older than Jesus and most likely just had become of age, so 13-20s.
Paul was a likely contemporary of the apostles and he was martyrs in 68-69, probably in his 50s. John, likely lived till as late as the late 90s, perhaps into his 80s....
Cool.
Then you will enjoy the read. Let me know what you think when ever you get around to reading it.
