Genesis 42:17-22

17So Joseph put them all in prison for three days.

18On the third day Joseph said to them, “I am a God-fearing man. If you do as I say, you will live.

19If you really are honest men, choose one of your brothers to remain in prison. The rest of you may go home with grain for your starving families.

20But you must bring your youngest brother back to me. This will prove that you are telling the truth, and you will not die.” To this they agreed.

21Speaking among themselves, they said, “Clearly we are being punished because of what we did to Joseph long ago. We saw his anguish when he pleaded for his life, but we wouldn’t listen. That’s why we’re in this trouble.”

22“Didn’t I tell you not to sin against the boy?” Reuben asked. “But you wouldn’t listen. And now we have to answer for his blood!”
