Ezekiel the prophet links Noah, Daniel and Job together (14:14) as righteous men. What was the connection?
Rashi and the rabbis explain that these three men saw their worlds destroyed, and then somehow found the wherewithal to rebuild. Noah, on a universal level (the utter destruction of civilization, then its subsequent rebuilding); Daniel, on a national Jewish level (from a Temple in its glory to its destruction, exile and then its rebuilding); and Job, on a personal level (painfully bereft of his flourishing personal life, only to find a way to rebuild a new one).
These three individuals were witnesses to the painful collapse and devastation of a world, and to living through its unlikely rebuilding.
