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:

'T is 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;

And earthly power doth then show likest God's

When mercy seasons justice.

- The Merchant of Venice, Act IV, Sc. 1
