וַתִּתֵּ֧ן אֶת־הַמַּטְעַמִּ֛ים וְאֶת־הַלֶּ֖חֶם אֲשֶׁ֣ר עָשָׂ֑תָה בְּיַ֖ד יַעֲקֹ֥ב בְּנָֽהּ׃
И она дала несладкую пищу и хлеб, который она приготовила, в руку своего сына Иакова.
Rashi
How many necks did Binyamin have: We do not follow [teach] this version. For this is the way of Scripture, to write, "necks," in the plural form, [as in] (Genesis 27:17), "upon the flat of his necks." [So here too] - "he cried upon his necks."
Haamek Davar
Like the sand of the sea. Through Yoseif’s wisdom or through Hashem’s will, the grain withstood the forces of decay for seven years, just as the sand withstands the waves.
