Genesis 42:17-22

17Then Joseph put his brothers in prison for three days.

18On the third day Joseph said to them, ‘Do what I say. Then you will stay alive, because I respect God.

19If you are honest men, let one of your brothers stay here in prison. The other brothers can go back to Canaan. You may take food back with you, because your families are hungry.

20But you must return to Egypt and you must bring your youngest brother to me. Then I will know that what you have said is true. Then you will not die.’ Joseph's brothers agreed to do what he told them.

21The brothers said to each other, ‘This punishment is happening to us because of what we did to Joseph. We saw how upset he was when he asked us not to kill him. But we refused to be kind to him. That is why we have all this trouble.’

22Reuben said, ‘I told you not to do anything bad to the boy. But you would not agree! We killed him and now we must receive the punishment.’
