וַיְצַ֣ו יוֹסֵ֗ף וַיְמַלְא֣וּ אֶת־כְּלֵיהֶם֮ בָּר֒ וּלְהָשִׁ֤יב כַּסְפֵּיהֶם֙ אִ֣ישׁ אֶל־שַׂקּ֔וֹ וְלָתֵ֥ת לָהֶ֛ם צֵדָ֖ה לַדָּ֑רֶךְ וַיַּ֥עַשׂ לָהֶ֖ם כֵּֽן׃
און יוֹסף האָט באַפֿױלן, מע זאָל אָנפֿילן זײערע כּלים מיט תּבואה, און אומקערן זײער געלט איטלעכן אין זײַן זאַק, און זײ געבן שפּײַז אױפֿן װעג. און מע האָט צו זײ אַזױ געטאָן.
Ramban
AND TO GIVE THEM PROVISION FOR THE WAY. The reason for saying this is so that they should not consume the food which they bought in the course of the journey. He informed them of this for he gave them the provisions for the journey in a kindly fashion so that they should be able to bring the brother [Benjamin] to him, for he said, “I have no intention of harming you if your words are verified.”
Radak
ויצו יוסף, he instructed his servants, the ones who were selling the grain (completing the transaction once it had been approved) to fill the brothers’ containers with grain, which they did. וימלאו; this is one of many verses in the Torah which has been written in an abbreviated manner.
Sforno
ולהשיב את כספיהם, and to restore their money. The plural mode in the word does not apply to the collective term כסף, money, but to the coins which together made up the money.
