Genesis 44:10-20

10 And he said, Now also let it be according unto your words; he with whom it is found shall be my slave, and ye shall be blameless.
11 Then they made haste, and each one took his sack down to the ground, and each one opened his sack.
12 And he searched and began at the eldest and finished at the youngest; and the cup was found in Benjamin’s sack.
13 Then they rent their clothes, and each one laded his ass, and they returned to the city.
14 And Judah and his brethren came to Joseph’s house, for he was yet there; and they fell before him on the ground.
15 And Joseph said unto them, What deed is this that ye have done? Know ye not that such a man as I can certainly divine?
16 Then Judah said, What shall we say unto my lord? What shall we speak or how shall we clear ourselves? God has found out the iniquity of thy slaves; behold, we are my lord’s slaves, both we and he also with whom the cup is found.
17 And he said, in no wise should I do so; but the man in whose hand the cup is found, he shall be my slave; and as for you, go up in peace unto your father.
18 Then Judah came near unto him and said, Oh my lord, let thy slave, I pray thee, speak a word in my lord’s ears, and let not thine anger burn against thy slave; for thou art even as Pharaoh.
19 My lord asked his slaves, saying, Have ye a father or a brother?
20 And we said unto my lord, We have a father, an old man, and a young man of his old age, yet a lad; and his brother is dead, and he alone is left of his mother, and his father loves him.
