Webster(i)
14 And Joseph said to them, That is what I spoke to you, saying, Ye are spies:
15 By this ye shall be proved: By the life of Pharaoh ye shall not go forth hence, except your youngest brother shall come hither.
16 Send one of you, and let him bring your brother, and ye shall be kept in prison, that your words may be proved, whether there is 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.
