ציטירנדיקער פּירוש אויף בראשית 41:34

ופקדו, “and they shall appoint, etc.” This takes place after all those that have been allowed to return home have done so. The use of the root פקד to describe making appointments is first found in the advice Joseph gave to Pharaoh in Genesis 41,34.

1. AND THE ISRAELITES WENT UP IN ARMS: as in (Genesis 41 [:34]) "And he armed the land of Egypt" when there was sustenance for them that they were sustained on the further way, for they were fed for one month from food those [reserves] that they did not ask for [food] from [15th Nisan] until 15th Iyyar.

וחמושים, according to Rashi, the meaning of the word is: “armed.” According to Rashi, the fear of the Israelites was not due to their not having arms with which to defend themselves. They were well armed. You are not to wonder where the Israelites had taken all these arms from, arms which they used in the desert for several wars, starting immediately after they had crossed the sea of reeds and had been attacked by the Amalekites. They needed these arms again when the conquered the land of Canaan under the leadership of Joshua. An alternate explanation of the word: חמושים. The word refers to provisions for the journey. The word is used in Genesis 41,34, where it describes the provisions stored by Joseph in anticipation of the seven years of famine that were to follow the seven years of plenty. In practice this meant (according to tradition) that the dough the Israelites took with them lasted them a whole month until the 15th of lyar, when the heavenly food, the manna took over. The reason for the need for that miracle had been that G-d took the people on a detour through the desert. (Compare Mechilta)
