ויספר אל אביו ואל אחיו. לְאַחַר שֶׁסִּפֵּר אוֹתוֹ לְאֶחָיו חָזַר וְסִפְּרוֹ לְאָבִיו בִּפְנֵיהֶם:
ויספר אל אביו ואל אחיו AND HE TOLD IT TO HIS FATHER AND TO HIS BRETHREN — After he had related it to his brothers (see 5:9) he again related it to his father in their presence.
ויגער בו. לְפִי שֶׁהָיָה מֵטִיל שִׂנְאָה עָלָיו:
ויגער בו AND HIS FATHER REBUKED HIM because he was arousing hatred against himself by relating the dream.
הבוא נבוא. וַהֲלֹא אִמְּךָ כְבָר מֵתָה, וְהוּא לֹא הָיָה יוֹדֵעַ שֶׁהַדְּבָרִים מַגִּיעִין לְבִלְהָה שֶׁגִּדְּלַתּוּ כְּאִמּוֹ. וְרַבּוֹתֵינוּ לָמְדוּ מִכָּאן שֶׁאֵין חֲלוֹם בְּלֹא דְּבָרִים בְּטֵלִים, וְיַעֲקֹב נִתְכַּוֵּן לְהוֹצִיא הַדָּבָר מִלֵּב בָּנָיו שֶׁלֹּא יַקְנִיאוּהוּ, לְכָךְ אָמַר לוֹ הֲבוֹא נָבוֹא וְגוֹ' – כְּשֵׁם שֶׁאִי אֶפְשָׁר בְּאִמְּךָ כָּךְ הַשְּׁאָר הוּא בָטֵל:
הבוא נבוא SHALL WE INDEED COME — “Is not your mother long since dead?” He did not, however, understand that the statement really alluded to Bilhah who had brought him up as though she were his own mother (Genesis Rabbah 84:11). Our Rabbis inferred from here that there is no dream but has some absurd incidents (Berakhot 55). Jacob’s intention in pointing out the absurdity of Joseph’s mother, who was dead, bowing down to him was to make his sons forget the whole matter so that they should not envy him, and on this account he said to him, “Shall we indeed come etc.” — meaning, just as it (the fulfillment of the dream) is impossible in the case of your mother so the remainder of the dream is absurd.
