Psalms 33:1-2
"Sing joyfully to the Lord,
You righteous;
It is fitting for the upright to praise Him.
Praise the Lord with harp;
Make music to Him on the
'six-stringed guitar'."
Psalms 33:3-4
Sing unto Him a new song;
Play skillfully with a loud noise.
For thw Word of the Lord is right;
And all His works are done in truth. [ Lyrics from: http://www.lyricsmode.com/lyrics/e/evil_child/verses.html ]
