8:8ח׳:ח׳
1 א

וישלח את היונה. לְסוֹף ז' יָמִים שֶׁהֲרֵי כְתִיב וַיָּחֶל עוֹד ז' יָמִים אֲחֵרִים, מִכְּלַל זֶה אַתָּה לָמֵד שֶׁאַף בָּרִאשׁוֹנָה הוֹחִיל ז' יָמִים:

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.

וישלח. אֵין זֶה לְשׁוֹן שְׁלִיחוּת אֶלָּא לְשׁוֹן שִׁלּוּח, שִׁלְּחָהּ לָלֶכֶת לְדַרְכָּה, וּבְזוֹ יִרְאֶה אִם קַלּוּ הַמַּיִם, שֶׁאִם תִּמְצָא מָנוֹחַ לֹא תָשׁוּב אֵלָיו:

וישלח And HE SENT FORTH — This does not mean merely “sending on an errand”, but “sending away”, “letting go” — he freed her to go where she liked, and thus he could see whether the waters abated, because if she could find a resting place she would not return to him.
