The quality of mercy is not strained;
It droppeth as the gentle rain from heaven
Upon the place beneath.
It is twice blest; It blesseth him that gives and him that takes:
‘Tis mightiest in the mightiest; it becomes
The 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 enthronèd in the hearts of kings,
It is an attribute to God himself;

William Shakespeare, The Merchant of Venice, Act IV, Scene I
