Genesis 42:19

17He put them all together into custody for three days.

18Joseph said to them the third day, “Do this, and live, for I fear God.

19If you are honest men, then let one of your brothers be bound in your prison; but you go, carry grain for the famine of your houses.

20Bring your youngest brother to me; so will your words be verified, and you won’t die.” They did so.

21They said to one another, “We are certainly guilty concerning our brother, in that we saw the distress of his soul, when he begged us, and we wouldn’t listen. Therefore this distress has come upon us.”
