100th Psalm:
"Shout for joy to the Lord, all the earth. Worship the Lord with gladness; come before him with joyful songs. Know that the Lord is God. It is he who made us, and we are his; we are his people, the sheep of his pasture. Enter his gates with thanksgiving and his courts with praise; give thanks to him and praise his name. For the Lord is good and his love endures forever; his faithfulness continues through all generations."
