The answer is: His corn money and his silver cup

Gen 44:2

In the dramatic tale of Joseph and his brothers, a notable twist unfolds when Joseph concocts a clever test for his siblings. He commands his steward to fill Benjamin's sack not only with grain, a symbol of sustenance and provision, but also with his silver cup, a powerful object that can represent authority, wealth, or stepping into a place of importance.

This act is rich with meaning. First, it raises the question of loyalty and sacrifice. Joseph’s brothers once betrayed him and sold him into slavery, but what will they do when forced to protect their younger sibling, whom they can no longer abandon? The silver cup also adds a layer of irony; Joseph’s brothers are reminded of his past, where their own greed once warranted a callous decision against family. The circumstances offer a clarion call toward reflected righteousness and the value of changed hearts.

Further echoing the themes of this story, in Jewish tradition, silver is often emblematically linked to redemption. So, here the cup symbolizes how twisted choices can demand correction and reveal our true selves. Interestingly, culinary traditions in that era highlight the significance of hospitality, seen even in the cooler shadows of intrigue in this narrative. Joseph provides grain, a quote from earlier passages celebrating familial bonds, even amid complex human emotions. In this way, the tales intertwine showing redemption is always a food for thought—even metaphorical leftovers in life's drama!
