Shakespeare's Sonnets: Oh from what pow'r hast thou this pow'rful might

Oh from what pow'r hast thou this pow'rful mightWith insufficiency my heart to sway,To make me give the lie to my true sightAnd swear that brightness doth not grace the day?Whence hast thou this becoming of things illThat in the very refuse of thy deedsThere is such strength and warrantise of skillThat in my mind thy worst all best exceeds?Who taught thee how to make me love thee more,The more I hear and see just cause of hate?Oh, though I love what others do abhor,With others thou should'st not abhor my state. If thy unworthiness rais'd love in me, More worthy I to be belov'd of thee.
