It is thy will thy image should keep open

Is it thy will, thy image should keep open
My heavy eyelids to the weary night?
Dost thou desire my slumbers should be broken
While shadows like to thee do mock my sight?
Is it thy spirit that thou send'st from thee
So 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 watchman ever for thy sake:
For thee watch I, whilst thou dost wake elsewhere
From me far off, with others all too near
