Genesis 42:15-17

21st Century King James Version

¹⁵ Hereby ye shall be tested: by the life of Pharaoh ye shall not go forth hence, unless your youngest brother come hither.

¹⁶ Send one of you and let him fetch your brother; and ye shall be kept in prison, that your words may be tested, whether there be any truth in you; or else by the life of Pharaoh surely ye are spies!”

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