Sing joyfully to the LORD, you righteous; 
  it is fitting for the upright to praise him.  Praise the LORD with the harp; 
  make music to him on the ten-stringed lyre. 
Sing to him a new song; 
  play skillfully, and shout for joy. 
For the word of the LORD is right and true; 
  he is faithful in all he does. 
 

Psalm 33:1-4
