Charles Ellicott Commentary Genesis 9:29

"And all the days of Noah were nine hundred and fifty years: And he died." — Genesis 9:29 (ASV)

All the days of Noah. —While Noah attained the same age as the antediluvian patriarchs, 950 years, human life was fast diminishing. The whole lifetime of Shem was 600 years; that of Peleg, a few generations afterwards, only 239. After him, only one man, Terah, is described as living more than 200 years, and there is great doubt concerning his age. (See Note on Genesis 11:32.) Thus, before Shem’s death, the age of man was rapidly shortening, and things were settling down to that condition in which they are set before us in profane literature.
