Genesis 42:17-22

17Then he put them in jail for three days.

18On the third day Joseph said to them, “Do this, and you will live. I, too, fear God.

19If you are honest men, you will let one of your brothers stay here in prison. The rest of you will go and take grain back to your starving families.

20But you must bring me your youngest brother. This will show that you’ve been telling the truth. Then you won’t die.” So they agreed.

21They said to each other, “We’re surely being punished for what we did to our brother. We saw how troubled he was when he pleaded with us for mercy, but we wouldn’t listen. That’s why we’re in trouble now.”

22Reuben said to them, “Didn’t I tell you not to sin against the boy? But you wouldn’t listen. Now we must pay for this bloodshed.”
