Genesis 42:21-22

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.’
