וירדו אחי יוסף. וְלֹא כָתַב בְּנֵי יַעֲקֹב, מְלַמֵּד שֶׁהָיוּ מִתְחָרְטִים בִּמְכִירָתוֹ וְנָתְנוּ לִבָּם לְהִתְנַהֵג עִמּוֹ בְּאַחְוָה וְלִפְדּוֹתוֹ בְּכָל מָמוֹן שֶׁיִּפְסְקוּ עֲלֵיהֶם:
וירדו אחי יוסף AND JOSEPH S BRETHREN WENT DOWN — It does not call them “the sons of Jacob” (as in 5:5), thus suggesting that they regretted having sold him and that they had made up their mind to behave towards him in a brotherly manner and to redeem him at whatever price people might fix for them to pay (Midrash Tanchuma, Miketz 8).
עשרה. מַה תַּלְמוּד לוֹמַר, וַהֲלֹא כְתִיב וְאֶת בִּנְיָמִין אֲחִי יוֹסֵף לֹא שָׁלַח? אֶלָּא לְעִנְיַן הָאַחְוָה הָיוּ חֲלוּקִין לְי' שֶׁלֹּא הָיְתָה אַהֲבַת כֻּלָּם וְשִׂנְאַת כֻּלָּם שָׁוָה לוֹ; אֲבָל לְעִנְיַן לִשְׁבֹּר בָּר כֻּלָּם לֵב אֶחָד לָהֶם (בראשית רבה):
עשרה TEN — What is the mention of this number intended to tell us? Is it not written (Genesis 42:4) “but Benjamin, Joseph’s brother did he not send” (and we therefore know that only ten brothers went to Egypt)? But it means to suggest that so far as their feeling of brotherhood towards Joseph was concerned they were divided into ten, because the love and hatred that all of them bore him were not alike, where as in regard to buying corn they were at one and united (Genesis Rabbah 91:2).
