So, now I have confess'd that he is thine, <br /> And I myself am mortgaged to thy will, <br /> Myself I'll forfeit, so that other mine <br /> Thou wilt restore, to be my comfort still: <br /> But thou wilt not, nor he will not be free, <br /> For thou art covetous and he is kind; <br /> He learn'd but surety-like to write for me <br /> Under that bond that him as fast doth bind. <br /> The statute of thy beauty thou wilt take, <br /> Thou usurer, that put'st forth all to use, <br /> And sue a friend came debtor for my sake; <br /> So him I lose through my unkind abuse. <br /> Him have I lost; thou hast both him and me: <br /> He pays the whole, and yet am I not free.<br /><br />William Shakespeare<br /><br />http://www.poemhunter.com/poem/sonnet-cxxxiv/
