Genesis 42:20

but bring your youngest brother unto me; so shall your words be verified, and ye shall not die. Here the love of Joseph for his brothers appears. He assures them that the fear of God governs him, he bids them take up the grain for the needs of their family, and while he does not change his condition that he wants to see Benjamin before believing in their uprightness, he relieves the severity by demanding only one out of their midst as hostage, while he offers to dismiss the rest. If they were really repentant, he knew that this way of dealing with them would be sure to have the desired effect. And they did so; the-brethren agreed to this condition in its present form.
