Genesis 44:13-17

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

14And Judah and his brethren came to Joseph's house; and he was still there; and they fell down before him to the ground.

15And Joseph said to them, What deed is this which ye have done? Did ye not know that such a man as I can certainly divine?

16And Judah said, What shall we say to my lord? what shall we speak, and how justify ourselves? 1God has found out the iniquity of thy servants; behold, we are my lord's bondmen, both we, and he in whose hand the cup has been found.

17And he said, Far be it from me to do so! The man in whose hand the cup has been found, he shall be my bondman; but as for you, go up in peace to your father.
