Genesis 42:18

¹⁶Send 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.

¹⁷And he put them all together into ward three days.

— Genesis 42:18 —

¹⁹If 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:

²⁰But bring your youngest brother unto me; so shall your words be verified, and ye shall not die. And they did so.
