The quality of mercy is not strained;

It droppeth as the gentle rain from heaven

Upon the place beneath. It is twice blessed—

It blesseth him that gives, and him that takes.

–William Shakespeare

 Have mercy upon me, O Lord; for I am weak: Lord, heal me; for my bones are vexed.

– Psalm 6:2

God be merciful unto us, and bless; and cause his face to shine upon us. 

– Psalm 67:1
