O sing joyfully
O sing joyfully unto God our strength :
make a cheerful noise unto the God of Jacob.
Take the song, bring hither the tabret :
the merry harp with the lute.
Blow up the trumpet in the new-moon :
even in the time appointed, and upon our solemn feast-day.
For this was made a statute for Israel :
and a law of the God of Jacob.
Psalm 81 vv.1-4
