The quality of mercy is not strain'd;
It droppeth, as the gentle rain from heaven
Upon the place beneath: it is twice bless'd;
It blesseth him that gives, and him that takes:
'T is mightiest in the mightiest; it becomes
The throned monarch better than his crown.
SHAKS.: _M. of Venice,_ Act iv., Sc. 1.
Who will not mercie unto others show,
How can he mercy ever hope to have?
SPENSER: _Faerie Queene,_ Bk. v., Canto ii., St. 42.
