William Shakespeare said this quote

The quality of mercy is not strained;It droppeth as the gentle rain from heavenUpon the place beneath. It is twice blessed;It blesseth him that gives, and him that takes.'Tis mightiest in the mightiest; it becomesThe throned monarch better than his crown; * * * * *It is enthroned in the hearts of kings;It is an attribute to God himself.
