Genesis 11:10-26

Genesis 11:10-26 starts of a new tablet listing direct ancestry line from Shem to Abraham. The Genealogy shows an immediate drop in life span following the flood, Shem who was born 98 years before the flood lived just 600 years as opposed to 800+ years for his ancestors. Also for those born after the Flood there was a further drop to less than 500 years. And following Babel; as indicated by Peleg; there was a sudden drop of 200 years.
