(KJV)

Serve the LORD with gladness:
come before his presence with singing.
Know ye that the LORD he is God:
it is he that hath made us,
and not we ourselves;
we are his people,
and the sheep of his pasture.

Enter into his gates with thanksgiving,
and into his courts with praise:
be thankful unto him, and bless his name.
For the LORD is good;
his mercy is everlasting;
and his truth endureth to all generations.
