From Samson Agonistes:  Second Selection

All is best, though we oft doubt,

What th' unsearchable dispose

Of highest wisdom brings about,

And ever best found in the close.

Oft he seems to hide his face,

But unexpectedly returns

And to his faithful Champion hath in place

Bore witness gloriously; whence Gaza mourns

And all that band them to resist

His uncontroulable intent.
