Shakespeare's Sonnets: Sweet love, renew thy force, be it not said

Sweet love, renew thy force, be it not saidThy edge should blunter be than appetite,Which but to-day by feeding is allayed,To-morrow sharp'ned in his former might.So, love, be thou, although to-day thou fillThy hungry eyes ev'n till they wink with fullness.To-morrow see again and do not killThe spirit of love with a perpetual dullness:Let this sad int'rim like the ocean beWhich parts the shore, where two contracted newCome daily to the banks, that when they seeReturn of love, more blest may be the view. As call it winter, which being full of care, Makes summers welcome, thrice more wish'd, more rare.
