Genesis 44:12

The manager also found the money that was in the top of each sack. But the cup was very much more important than the money. So the manager did not mention the money.

Judah appeals to Joseph

v14 When Judah and his brothers reached Joseph’s house, Joseph was still there. They fell to the ground in front of him. v15 Joseph said to them, ‘You have done an evil deed. You should have known that a man like me can certainly find the truth by magic.’ v16 And Judah said, ‘We do not know what to say to my master. We do not know how to speak. We cannot show that we are honest. God has shown that we are guilty. We are my master’s slaves. Both we and the one who had the cup are my master’s slaves.’ v17 But Joseph said, ‘I would certainly not do that! Only the man who had the cup shall be my slave. But you other men, go in peace to your father.’
