베레시트 (창세기) 8:14

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.

וּבַחֹ֙דֶשׁ֙ הַשֵּׁנִ֔י בְּשִׁבְעָ֧ה וְעֶשְׂרִ֛ים י֖וֹם לַחֹ֑דֶשׁ יָבְשָׁ֖ה הָאָֽרֶץ׃ {ס}        

And in the second month, on the twenty-seventh day of the month, was the earth dried.
