Genesis 44:8-12

Behold, the money which we found in the opening of our sacks we have brought back to you from the land of Canaan. How then could we steal silver or gold from your lord’s house?

With whomever of your servants it is found, he shall die, and we also shall be my lord’s slaves.”

So he said, “Now let it indeed be according to your words; he with whom it is found shall be my slave, but the rest of you shall be considered innocent.”

Then they hurried, each man lowered his sack to the ground, and each man opened his sack.

And he searched, beginning with the oldest and ending with the youngest; and the cup was found in Benjamin’s sack.
