ותרעב כל ארץ מצרים. שֶׁהִרְקִיבָה תְבוּאָתָם שֶׁאָצְרוּ חוּץ מִשֶּׁל יוֹסֵף:
ותרעב כל ארץ מצרים AND THE LAND OF EGYPT WAS FAMISHED — for all the grain they had stored up rotted except that of Joseph (cf. Genesis Rabbah 91:5)
כל אשר יאמר לכם תעשו. הֲרֵי גָּזַר עַל הַתְּבוּאָה וְהִרְקִיבָה, מַה אִם יִגְזֹר עָלֵינוּ וְנָמוּת.
אשר יאמר לכם תעשו WHAT HE SAITH TO YOU, DO — He gave them this order because Joseph had told them to be circumcised. When they came to Pharaoh and said, “Thus he bids us do otherwise he will give us no corn”, he asked them, “Why did you yourselves not lay up corn? Did he not publicly announce that years of famine were coming?” They answered him, “We gathered in much, but it has rotted”. He said to them, “If this be so — what he saith to you, do. See, he laid a decree upon the produce and it rotted; what will happen if he lays a decree upon us that we should die!” (cf. Genesis Rabbah 91:5)
