וַיְשַׁלַּ֥ח אֶת־הַיּוֹנָ֖ה מֵאִתּ֑וֹ לִרְאוֹת֙ הֲקַ֣לּוּ הַמַּ֔יִם מֵעַ֖ל פְּנֵ֥י הָֽאֲדָמָֽה׃
Mandò fuori la colomba, per vedere se le acque erano scemate sulla faccia della terra.
Rashi on Genesis
וישלח את היונה AND HE SENT FORTH A DOVE at the end of seven days, for it is written, (Genesis 8:10) “And he stayed yet other seven days” — from this statement you may infer that after the first occasion, also, he waited seven days.
Sforno on Genesis
וישלח את היונה, all of the seven pairs of pigeons [based on the latter ה in front of the word יונה. Ed.]
