His days will be one hundred and twenty years (Genesis 6:3)
The flood signals the end of the lengthy lifespans of men. Whereas the lifespans of the men listed in Genesis 5 averaged roughly 950 years each, those that follow Noah and precede Babel are roughly 450 years, and after Babel, they drop to about 200 years. Eventually, of course, the average lifespan dips below 100. The lifespan of 120 years seems to be the “ideal life” (e.g., Moses—Deut 34:7). This American Colony photo of an elderly Bedouin man was taken between 1898 and 1946.
