Joseph has set up the brothers by putting the cup in Benjamin’s sack. Back when Joseph was a part of the family, the brothers would have gladly given Joseph up to be a slave had the scenario presented itself. Now it’s their father’s other favorite son. It’s clear that the brothers are distraught and repentant over the thought of hurting their father by losing his last favorite son Benjamin. Judah, who was the one whose idea it was to sell Joseph in chapter 38 is now the one who wants to sacrifice himself for Benjamin.
