Genesis 44:13 (KJV)

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?

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

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

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

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

And Judah and his brethren came to Joseph's house; for he was yet there: and they fell before him on the ground.

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.

And he said, God forbid that I should do so: but the man in whose hand the cup is found, he shall be my servant; and as for you, get you up in peace unto your father.

Then Judah came near unto him, and said, Oh my lord, let thy servant, I pray thee, speak a word in my lord's ears, and let not thine anger burn against thy servant: for thou art even as Pharaoh.
