The pow'r that sits above the stars I fear
(He said) nor shall you find injustice here:
To prove that you have no clandestine view,
Nor hostile aim, but are to honour true,
One of your kindred number left behind,
Th' attending guards shall as an hostage bind;
Secure from wrong, the captive shall remain,
If at set limits you return again:
But be for ever exiles from the place,
Nor ever hope again to see my face,
Unless you bring your youngest brother here,
No more on  fatal coast appear:
Be this a proof your words have no disguise,
Or you by  sacred life are spies.
