Read it through once

FERDINAND. So they are: My spirits, as in a dream, are all bound up. My father’s loss, the weakness which I feel, The wrack of all my friends, nor this man’s threats, To whom I am subdued, are but light to me, Might I but through my prison once a day Behold this maid: all corners else o’ th’ earth Let liberty make use of; space enough Have I in such a prison.
