Genesis 44:9-12

9If any of your servants is found to have it, he will die; and the rest of us will become my lord’s slaves.” 10“Very well, then,” he said, “let it be as you say. Whoever is found to have it will become my slave; the rest of you will be free from blame.” 11Each of them quickly lowered his sack to the ground and opened it. 12Then the steward proceeded to search, beginning with the oldest and ending with the youngest. And the cup was found in Benjamin’s sack.
