Genesis 44:14

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

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

And Joseph said unto them, What deed [is] this that ye have done? wot ye not that such a man as I can certainly divine?

And Judah said, What shall we say unto my lord? what shall we speak? or how shall we clear ourselves? God hath found out the iniquity of thy servants: behold, we [are] my lord's servants, both we, and [he] also with whom the cup is found.
