וְ֠הָבִיאוּ אֶת־אֲחִיכֶ֣ם הַקָּטֹן֮ אֵלַי֒ וְאֵֽדְעָ֗ה כִּ֣י לֹ֤א מְרַגְּלִים֙ אַתֶּ֔ם כִּ֥י כֵנִ֖ים אַתֶּ֑ם אֶת־אֲחִיכֶם֙ אֶתֵּ֣ן לָכֶ֔ם וְאֶת־הָאָ֖רֶץ תִּסְחָֽרוּ׃
puis, amenez-moi votre jeune frère et je saurai que vous n’êtes pas des espions, que vous êtes d’honnêtes gens; je vous rendrai votre frère et vous pourrez circuler dans le pays.’
Or HaChaim
ויאמנו דבריכם. "And your words will be verified." This means that if the brothers did not agree it would prove their guilt and that that was the reason they did not dare leave one brother behind. Moreover, it would be forbidden to hand over an unnamed individual if there was a likelihood he was guilty of the death penalty. Another possible meaning of these words is simply that by bringing Benjamin down to Egypt Joseph would make sure their families would not die of starvation. The brothers referred to this when they told their father in verse 34 that Joseph had offered ואת הארץ תסחרו, "you may travel freely in the land."
