Genesis 44:1-3

1When his brothers were ready to leave, Joseph gave these instructions to his palace manager: “Fill each of their sacks with as much grain as they can carry, and put each man’s money back into his sack.

2Then put my personal silver cup at the top of the youngest brother’s sack, along with the money for his grain.” So the manager did as Joseph instructed him.

3The brothers were up at dawn and were sent on their journey with their loaded donkeys.
