It is stated that Noah lived for 950 years. The age of Noah when he died was detailed in Genesis 9:29. This puts Noah at only a few years younger than the oldest living man in the Bible, Methuselah, who lived to be 969 years old.
Noah lived much longer than his own father, Lamech, who lived to be 777 years old. Before the flood, God had designed man to live without sin, and thus live forever. After the flood, men in biblical times started living a much shorter lifespan. The oldest living man after the flood was Shem, who lived to 600.
