What is the meaning of "ka'Avur Sufah v'Ein Rasha"?
Rashi: A storm wind comes suddenly, and the Rasha is cut off from his place. Malbim - his existence is haphazard, without a strong root. Something without a strong root, a storm wind takes it away. When years are normal, he lives based on nature, but when there is turmoil, he is cast from his place.
R. Yonah: A light passing occurrence displaces him like a storm wind, like chaff is cast off in a moment.
Malbim citing Bereishis Rabah (30:1): This refers to Dor ha'Mabul.
What do we learn from "v'Tzadik Yesod Olam"?
Yuma 38b: The world exists even for the sake of one Tzadik.
R. Yonah: A Tzadik's virtue saves him from afflictions. It saves also the world, and the world is founded on him - "Yimalet Iy Naki v'Nimlat b'Vor Kapecha" (Iyov 22:20).
Malbim: His existence is due to the perfection of his Nefesh and Hashem's Hashgachah. At a time of a storm wind, not only does wind and events of the time not move him, for he is a solid foundation - he is a foundation for the entire world! Bereishis Rabah (30:1) applies our verse to Noach.
