Genesis 42:17-22

17And he put them all together in custody for three days.

18On the third day Joseph said to them, "Do this and you will live, for I fear God:

19if you are honest men, let one of your brothers remain confined where you are in custody, and let the rest go and carry grain for the famine of your households,

20and bring your youngest brother to me. So your words will be verified, and you shall not die." And they did so.

21Then they said to one another, "In truth we are guilty concerning our brother, in that we saw the distress of his soul, when he begged us and we did not listen. That is why this distress has come upon us."

22And Reuben answered them, "Did I not tell you not to sin against the boy? But you did not listen. So now there comes a reckoning for his blood."
