Shakespeare's Sonnets: Is it thy will thy image should keep op'n

Is it thy will thy image should keep op'nMy heavy eyelids to the weary night?Dost thou desire my slumbers should be brok'n,While shadows like to thee do mock my sight?Is it thy spirit that thou send'st from theeSo far from home into my deeds to pry,To find out shames and idle hours in me,The scope and tenor of thy jealousy?O no, thy love, though much, is not so great,It is my love that keeps mine eye awake,Mine own true love that doth my rest defeat,To play the watch-man ever for thy sake. For thee watch I, whil'st thou dost wake elsewhere, From me far off, with others all too near.
