And Joseph said unto them, That is it that I spake unto you, saying, Ye are spies:

Hereby ye shall be proved: By the life of Pharaoh ye shall not go forth hence, except your youngest brother come hither.

Send one of you, and let him fetch your brother, and ye 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 ye are spies.

And Joseph said unto them the third day, This do, and live; for I fear God:

If ye be true men, let one of your brethren be bound in the house of your prison: go ye, carry corn for the famine of your houses:

But bring your youngest brother unto me; so shall your words be verified, and ye shall not die. And they did so.
