Komentaryong Sumisipi para sa Genesis 18:32

"And they shall cover themselves," "and they shall call out [to God]"- [The king's proclamation said:] "Any man who is a knowledgeable person, or someone who knows they have done evil," or [the decree was saying] like [that which it says when Avraham entreated God regarding Sodom] "Perhaps [there are ten good men to be found there?]" (Bereshit 18:32).

I would have to burden him to build many arks. Maharam Yafeh objected: On the contrary, if they would be righteous, together with their wives they would be more than ten and would protect the world, and no arks would be needed! For Rashi explains in Parshas Vayera (18:32) that Avraham did not pray [for Sedom to be saved] for less than ten tzaddikim, since [he knew that] the generation of the Flood had eight tzaddikim, and it did not save their generation. This implies that ten tzaddikim would save their generation. The answer is: Ten tzaddikim would not save the whole generation from the Flood; they would save their city only. Consequently, “I would have to burden him to build many arks” for all the inhabitants of their city, as the Flood would still come and wipe out the rest of the world. (Tzeidah L’Derech)
