The pasuk itself, Mishlei 24:16, contrasts the righteous person who falls seven times and rises with the wicked who are tripped by a single misfortune.
Ibn Ezra (Mishlei 24:16) reads "seven" as idiomatic for "many" — paralleling the phrase "many evils befall the righteous" — and understands "rises" as meaning that God saves him from all of them, while the wicked stumble through the very evil they plotted against the righteous.
The Ralbag (Mishlei 24:16) emphasizes the providential dimension: the righteous falls many times yet rises each time because Divine providence clings to him, whereas the wicked fall from a single misfortune and do not recover.
The Malbim (Mishlei 24:16) specifies that the righteous rises "through God's help," and adds that the wicked — even when they are many — are ultimately felled by the very evil they prepared against the righteous, from which they do not recover.
Yalkut Shimoni on Nach 286 supplies a Midrashic counterpoint: a single punishment is enough to destroy the wicked entirely — proof being that the Torah writes "in judgment" (singular), not "in judgments" — whereas the righteous can endure seven falls and still rise, confirming that one calamity suffices to undo the wicked where seven cannot undo the righteous.
