Shakespeare's Sonnets: O call not me to justify the wrong

O call not me to justify the wrongThat thy unkindness lays upon my heart;Wound me not with thine eye but with thy tongue;Use pow'r with pow'r and slay me not by art.Tell me thou lov'st else-where, but in my sight,Dear heart, forbear to glance thine eye aside.What need'st thou wound with cunning when thy mightIs more than my o'er-press't defence can bide?Let me excuse thee: ah, my love well knowsHer pretty looks have been mine enemies,And therefore from my face she turns my foesThat they else-where might dart their injuries. Yet do not so but, since I am near slain, Kill me out-right with looks and rid my pain.
