Psalm 32:11; 33:1-3 (NIV 1984)
Rejoice in the Lord and be glad, you righteous;
sing, all you who are upright in heart!
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.
