וימחו מן הארץ., נמחה שמם מן הארץ, כי אין להם זרע: וישאר. ונשאר רק נח לבדו ואשר אתו והנה זאת תשובה גמורה על חסירי דעת מאחינו שאומרים שלא היה המבול בכל הארץ: AND THEY WERE BLOTTED OUT. Their names were erased from the earth because they left no descendants. [AND NOAH ONLY WAS LEFT.] Only Noah and those with him were left. This verse proves how wrong are some of our ignorant brethren who maintain that the flood did not cover the entire earth.27Some say this alludes to those who maintain that a certain high mountain in Greece was not covered by the flood; others, to the Rabbinic sages who said that the land of Israel was not covered by the flood. See Zebahim 113b; Bereshit Rabbah 33:9. However, Weiser doubts that I.E. would express himself so strongly against the Rabbinic sages. Others say that I.E. directed his barb against those who take the Rabbinic statement literally.
