וַֽיְהִ֧י הַמַּבּ֛וּל אַרְבָּעִ֥ים י֖וֹם עַל־הָאָ֑רֶץ וַיִּרְבּ֣וּ הַמַּ֗יִם וַיִּשְׂאוּ֙ אֶת־הַתֵּבָ֔ה וַתָּ֖רָם מֵעַ֥ל הָאָֽרֶץ׃
Le Déluge ayant duré quarante jours sur la terre, les eaux, devenues grosses, soulevèrent l’arche, qui se trouva au-dessus de la terre.
Rashi
ויהי הגשם על הארץ AND THE RAIN WAS UPON THE EARTH — But later on (v. 17) it says. “And the Flood was upon the earth”! But the explanation is this: when He poured down the water at first He made it fall in mercy (gently), in order that if the people would repent, it might prove a rain of blessing; but when they did not repent it became a destructive flood (Genesis Rabbah 31:12) .
