William Shakespeare said this quote

“ The quality of mercy is not strain'd,It droppeth as the gentle rain from heavenUpon the place beneath: it is twice blest;It blesseth him that gives and him that takes:'Tis mightiest in the mightiest: it becomesThe throned monarch better than his crown;His sceptre shows the force of temporal power,The attribute to awe and majesty,Wherein doth sit the dread and fear of kings;But mercy is above this sceptred sway;It is enthroned in the hearts of kings,It is an attribute to God himself;And earthly power doth then show likest God'sWhen mercy seasons justice. ”
