Psalm 81:1-4 KJV
Sing aloud unto God our strength:
Make a joyful noise unto the God of Jacob.
Take a psalm, and bring hither the timbrel,
The pleasant harp with the psaltery.
Blow up the trumpet in the new moon,
In the time appointed, on our solemn feast day.
For this was a statute for Israel,
And a law of the God of Jacob.
