William Shakespeare, Sonnet lxxxvii

Farewell! thou art too dear for my possessing,
And like enough thou know'st thy estimate:
The charter of thy worth gives thee releasing;
4
My bonds in thee are all determinate.
For how do I hold thee but by thy granting?
And for that riches where is my deserving?
The cause of this fair gift in me is wanting,
8
And so my patent back again is swerving.
Thyself thou gav'st, thy own worth then not knowing,
Or me, to whom thou gav'st it, else mistaking;
So thy great gift, upon misprision growing,
12
Comes home again, on better judgement making.
Thus have I had thee, as a dream doth flatter,
In sleep a king, but, waking, no such matter.
