A sudden, premature end often serves as a stark warning against a life of wickedness and rebellion. The total destruction of the generation of the Flood stands as the ultimate example of this abrupt downfall. The primary approach among commentators is that these wicked individuals faced absolute destruction and death [רש״י, רלב״ג, אבן עזרא, רמב״ן, מלבי״ם, שטיינזלץ]. Another perspective suggests a process of rapid physical deterioration, where the wicked aged quickly, their faces filling with wrinkles as they were removed from the world far before their natural time [מצודת דוד, מצודת ציון]. Regardless of the exact physical form it took, their end arrived while they were still young, long before their expected time to die.
Beyond the simple reality of an early death, a deeper argument about faith unfolds. The wicked might try to dismiss their punishment by claiming that the Flood was merely the result of natural laws, climate conditions, or astrological shifts, rather than a divine response to their actions [מלבי״ם]. To counter this, it is emphasized that their end came completely out of its natural sequence. The punishment was an act of direct providence from God, brought on by their heresy [רמב״ן]. As proof of His divine intervention, the natural world and the astrological systems completely ceased to function during the year of the Flood, making it impossible to blame the disaster on nature or the passage of time [אלשיך].
The method of their destruction was a mighty river pouring over their foundation. Most commentators agree this refers to the heavy waters of the Flood crashing down upon the wicked, while some note it also hints at the fire and brimstone that rained down upon the people of Sodom [רש״י].
This imagery of a river pouring over a foundation carries several layers of meaning. On a physical level, the solid, stable earth upon which humanity stood, the very foundation of their existence, melted and washed away, turning into a raging river that drowned them [אבן עזרא, מצודת דוד, רלב״ג, מלבי״ם]. Metaphorically, the rushing river represents the overwhelming speed with which the wicked were wiped out [רמב״ן]. Furthermore, it reveals a profound truth about their lives: they never truly had a stable base. Their foundation was always as fluid, shaky, and unstable as water [שטיינזלץ].
Finally, this destruction operated on a principle of measure for measure. The concept of a human foundation can also refer to the physical seed from which a person is formed. Because the generation of the Flood engaged in severe sexual immorality, corrupting their physical foundation, God judged them accordingly. The very foundation of their existence was transformed into boiling floodwaters that washed them entirely away [אלשיך].
