14 And Joseph said unto them, It is as I spoke unto you, saying, You are spies:
15 Hereby you shall be proved: By the life of Pharaoh you shall not go forth from here, except your youngest brother come here.
16 Send one of you, and let him fetch your brother, and you shall be kept in prison, that your words may be proved, whether there be any truth in you: or else by the life of Pharaoh surely you are spies.
17 And he put them all together into custody three days.
18 And Joseph said unto them the third day, This do, and live; for I fear God:
19 If you be true men, let one of your brothers be bound in the house of your prison: go, carry grain for the famine of your houses:
20 But bring your youngest brother unto me; so shall your words be verified, and you shall not die. And they did so.
