Genesis 44:10

7 And they said unto him, Wherefore speaketh my lord such words as these? Far be it from thy servants that they should do such a thing.

8 Behold, the money, which we found in our sacks` mouths, we brought again unto thee out of the land of Canaan: how then should we steal out of thy lord`s house silver or gold?

9 With whomsoever of thy servants it be found, let him die, and we also will be my lord`s bondmen.

10 And he said, Now also let it be according unto your words: he with whom it is found shall be my bondman; and ye shall be blameless.

11 Then they hasted, and took down every man his sack to the ground, and opened every man his sack.

12 And he searched, [and] began at the eldest, and left off at the youngest: and the cup was found in Benjamin`s sack.

13 Then they rent their clothes, and laded every man his ass, and returned to the city.
