Genesis 42:17-24

And he put them all together in custody for three days. On the third day Joseph said to them, “Do this and you will live, for I fear God: if 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, and bring your youngest brother to me. So your words will be verified, and you shall not die.” And they did so. Then 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.” And 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.” They did not know that Joseph understood them, for there was an interpreter between them. Then he turned away from them and wept. And he returned to them and spoke to them. And he took Simeon from them and bound him before their eyes.
