בשבעה ועשרים. יְרִידָתָן בַּחֹדֶשׁ הַשֵּׁנִי בְי"ז בַּחֹדֶשׁ, אֵלּוּ י"א יָמִים שֶׁהַחַמָּה יְתֵרָה עַל הַלְּבָנָה, שֶׁמִּשְׁפַּט דוֹר הַמַּבּוּל שָׁנָה תְמִימָה הָיָה:

בשבעה ועשרים ON THE TWENTY-SEVENTH [OF THE MONTH] —The rain had begun to fall in the second month on the seventeenth day (Genesis 7:11): the ten days are those by which the solar year exceeds the lunar year; for the punishment of the generation of the Flood lasted a full (i.e. a solar) year (Genesis Rabbah 33:17).

יבשה WAS [THE EARTH] DRIED — It became hard as is its normal condition.
